@@stonesaquatichomes6825 considering he said he'd grown one out himself and he's big into monster fish, I doubt he was keeping a ghost knife in a 20 gallon at his store (that's B roll from his store)
So funny, I literally just told my boyfriend that if we could ever get a large tank this one of the fish I’d want! I just think they’re so cool looking! And then here’s the co op care video lol. One day... one day...
To me this fish is a puppy, if he likes you he will come out and look at you and even play with you and sleep on your hand if they fancy. Pretty smart fish, if not the smartest fish in the hobby.
I remember being a little kid and going into the pet store and looking at the fish was always my favorite part of the week. The knifefish was the first fish that ever caught my interest and made me want to keep fish but I never knew what they were called until just now. Thank you for this. When I get a house big enough, I'm going to look into getting one of these. I just think they're so cool.
You always have that perfect timing. This is a dream fish and I've wanted one for over 5 years. I'm getting one very soon, for the 145 gallon I'm getting.
Love the care guides. Another fish that I would love to see a care guide/species spotlight for is the freshwater archerfish. There is very little online about archers. Loved when you had them in the 800
I kept Ghosts in the '70's. Glad to see that they have finally solved the breeding problem. Back then no one had any idea how to breed them, or even sex them.
I managed to keep five together in a large tank with lots of branches and i mean lots of branches,yes they will spare with each other now and again but in the group it is spread out. I had them up to 15" before rehousing them. They love mussles prawns and blood worms. Great fish and can be trained too eat from fingers if feeding mussle.
This was my first ever fish I actually picked out. ( mom and grandfather helped, owned a pet store) and I miss it dearly. I kept him with a Dino bichir they got along great! I look forward to getting a large tank and get one again. We had my knife Trained to follow my finger just before meal times to help check him for problems. Trained to eat from my fingers as well. I love these fish!
I love how my ghost knife LOVES his heavily planted tank stocked with plants from aquarium coops site. And loves to pink on his tank mates Always front and center day and night and he’s very fun to watch and enjoy!
Great video, I have one BGK and I love seeing him in my 125g aquarium. My question is, what pleco is in 6;41 of the video? He is really beautiful. Again, thanks for the video
Had a knife fish when I first started fish keeping around 15 years ago. Every morning I would check the tank before heading to uni and started to notice one by one each of my cardinal tetras were loosing their eyes. I invested in a red light and recorder the tank overnight. The knife fish came out straight after lights out and hunted for the little fish eyes. When the fish died of stress, he then ate the fins etc. Vicious fish in my experience
I bought mine as a baby about 4 years ago when I used to work at a pet store. The second I saw it eating flake food I knew I had to bring it home! Now he's about a foot long and on a steady diet of medium to large cichlid pellets, in my 80 gallon bowfront with a large (super calm) 14 year old mayan cichlid, a syno cat, and some glofish tetras 😂
I had a brown 'ghost knife'. Looked the same but just brown. Even though I knew it couldn't see very well if at all, it seemed to know when I went by the tank and would come to the surface and if I put my hand in it liked to rub against me. Other people could walk by and it wouldn't react. They seem quite smart and the way they swim is very interesting.
I'm such a big fan of anything cory is in! I could careless about the fish but since cory is talking about it I'm there. Lol anything dean or cory has to do with I'm there..
Had mine for a month now in a community tank with a common pleco that’s about 7 inches now and 5 Corys he’s doing amazing then pleco and the Cory’s and him all get along I’ve sat there and observed them he is very active day and night i feed him blood warms and I sometimes I hear that smacking noise which is him eating the snails!!! Haha they love snails too!!!
thank you so much my little brother brought home one last night its very small the smallest ive ever seen so hes in a 2 gallon aquarium for now will up grade once i know hes healthy and eating
@@mrlazli it ended up dying eventually lol but they do live a long time and grow to be about 8-10 inches if you feed it well. Maybe bigger idk all fish are different some become monsters im sure this one has the potential.
I got a black ghost 5 years ago, he/she is only 9" I think having to heat treat ick stunted the growth. Still incredible fish. He knows when I'm close to his glass side of his tunnels
My brother just called me from Ohio and told me to look up a video of a clown knife fish to see how cool it swims. I found this video and can see what he is talking about from Florida. Awesome looking fish! I really like that pleco you have too!
Another tip I have found is don’t keep them with long finned fish. They kinda go into a feeding frenzy at feed time and may mistakenly bite the fins of some fish. Mine would often do this to my Angels, so I had to move him to a another tank.
Saw a tru of knife fish on display at my bigger lfs. Had never seen them in real life before but instantly recognized them as those little “knifes”. Would love to have one one day.
Cory talks fast... But, he said a Very important thing for newer and experienced fish keepers alike. When you have more than one negative factor happening in your tank for a particular fish, it will become more prone to disease or illness. Temperature, PH, hardness, stress from other fish or a lack of feeling safe... Not enough food or poor diet compared to the needs of the fish... Monitor the behaviors of your fish.. Test your water. Have an easy to read thermometer, that you can see every time you feed your aquarium. And, don't be afraid to ask questions, if any of your fish are acting like something may be wrong. Cheers!
Got a baby ghost knife put him in a starter 30 gallon but then realized after 2 years he had stunted growth and only grew to a max of 5 inches still got the buddy.
Thank you! Day one with my little buddy in my 55gal, will definitely be getting a 75 gallon (to be my 8th crystal-clear beautiful tank thanks to you!). I was worried about him because he was spazzing out when i put him in and looked like was dying at the botton just after 5 minutes in... Turned off the lights, within a few minutes he was up and exploring. It's been 5 hours now and he is up and about exploring all over the place. I reeeeeally hope he makes it to tomorrow, if he does, he should be good!
Great run down on this fish!! How interesting and I don't know if I've got the skills to keep one or not but it's something I definitely would love to consider! One of my dream fish for sure! Thanks Cory for all the information you provide! I hope you and your family are having a happy holidays!!🙏😍🌿🐟🎄🌿💚
I know this is a little bit old but ghost knives and elephantnose et al, do not have sonar They have active electrolocation and they do not disrupt each other when they are in proximity due to what is known as an jamming avoidance response, where one fish will lower the frequency of its field and the other will raise it, though I am not sure that this works across different species (ie an elephantnose and a ghost knife)
I have had a ghost knife named koko in my 36 gallon for about two years and he hasn’t shown any signs of growth defects and he loves his food. I am planning on getting him into a larger aquarium in the next couple months or in the next year.( depends on how much money I can spend and where I will have a perfect place to keep it
Ya right probably because it's dead, why I mean 36gallons?!??!? Like u are the kind of person who will put 50goldfish in a bowl with pink gravel, how is a fish that grows up to 20inches living happy and healthy in a 36gallon!?!??! Like what that's just wow look at the levels of non intellectual life forms
@@thefishcraftian5389 mine is in a 30 gallon but thats because both he and my arrowana are both babies that would get eaten in my 220 at their current size of about 4 inches each, once they grow a little more and get to the propper size they will get moved to the big tank.
Tank mates I’ve had luck with are uaru, acara, discus, fire mouth, Denison barbs, boasmani rainbows, severum, geophagus, my original rainbow wolf fish, rainbow sharks, flag tail prochilodus, bichir, people say rays and arowana but haven’t personally tried
Really want to add one to my 125 gallon community tank I am just worried he will eat my zebra pleco one day when he is big enough. Anyone have experience with smaller plecos and black ghost knifes?
Mine never bothered my gold nugget pleco, if you make a lot of territory with driftwood since both knives and plecos are territorial they'll probably never scrap with each other.
Yeah, I definitely messed up when I purchased two of these little fellas. I did exactly what you said we shouldn't do. I bought two and, of course they fought. I also did the other thing that you said not to do and put them in with jaguar and convict cichlids and that proved to be fatal for both of them, so yeah don't do that. They might all be from South/Central America but they definitely aren't compatible.
i have a african knifefish and its my smartest fish they love to come out and look back at me when im looking at the tank and they avoid my other family members and seem to only be comfortable looking at me since i stay up at night and tend to stare at the tank while i eat and smoke so hes gotten used to looking at me and being seen by me but hes skiddish to everyone else it makes me think hes smart
Oof is this the video with a care package if so I would love one I just bought 2 apisto caves, sponge filter and xtreme krill food from you guys so another Christmas present would be cool
It's funny cuz what stops me from getting one is its activity habits lol since it is nocturnal, i would feed it at night, so im thinking if i will b able to do that with working 2 jobs lol
Boy I wish the pet store had told us that this may not be good for use, she said noughting. So now I have only my ghost knife, and to start with I thought was he had died because he was just laying over the plants, but oh no I came back to get him out and he was swinging around just fine. I love this fish but didn't have a clue how big he would be, so now working to get another take for him. Would angelfish be a good tank mate for him?
Thank you Corey. I have been thinking about a ghost knife for a while. Now after seeing that I will wait till I am able to get my 40 gallon going before i get one
If they're big enough, they'll eat a cube of tubifex worms in one bite. My big boy recently passed away when I set up a new tank ;( But I got a new baby black ghost knife fish, he's doing great!
I've kept these guys for years. they are super easy to keep but I still wouldn't recommend for beginners. Most beginners don't appreciate how big they get and that they will eat literally anything that fits in their mouths, including each other
Whatever you do don't keep them with anything that's smaller than 3". They don't look it and it can vary between individuals but most normal community fish will just be a quick mid night snack for them.

Thank you for the video and have a great Christmas
And they are awesome!
I've had mine going on 10 years now. Still healty and strong.
"...grown to about that big.." About how big, Cory?
Was thinking the same thing! 🤣
The size of that one in the video when he said that would be my guess pmsl 🤦♂️
@@stonesaquatichomes6825 considering he said he'd grown one out himself and he's big into monster fish, I doubt he was keeping a ghost knife in a 20 gallon at his store (that's B roll from his store)
They grow to about 20 inches (50 cm), according to google
They only grow to about 12-18" in captivity,even in the wild 20" ones are rare , 18" is more common.
So funny, I literally just told my boyfriend that if we could ever get a large tank this one of the fish I’d want! I just think they’re so cool looking! And then here’s the co op care video lol. One day... one day...
There are a knife fish that are smaller. But none are as cool looking as the ghost.
To me this fish is a puppy, if he likes you he will come out and look at you and even play with you and sleep on your hand if they fancy. Pretty smart fish, if not the smartest fish in the hobby.
Ikr!

Just started to raise one was really looking for a good care guide... I’m so glad this came out today !!! Couldn’t have been better timing
Love the care guides. Another fish that I would love to see a care guide/species spotlight for is the freshwater archerfish. There is very little online about archers. Loved when you had them in the 800
We were given our BGK lil over a year ago. Shes pushing 14 15 inches now adored and spoiled. Ty for makn the vid.
I kept Ghosts in the '70's. Glad to see that they have finally solved the breeding problem. Back then no one had any idea how to breed them, or even sex them.
I managed to keep five together in a large tank with lots of branches and i mean lots of branches,yes they will spare with each other now and again but in the group it is spread out.
I had them up to 15" before rehousing them.
They love mussles prawns and blood worms.
Great fish and can be trained too eat from fingers if feeding mussle.
definitely one of my favourite fish, i sold mine this year bc i went to Uni. He was about 13-14 inches, absolutely massive
This was my first ever fish I actually picked out. ( mom and grandfather helped, owned a pet store) and I miss it dearly. I kept him with a Dino bichir they got along great! I look forward to getting a large tank and get one again.
We had my knife Trained to follow my finger just before meal times to help check him for problems. Trained to eat from my fingers as well.
I love these fish!
Merry Christmas, Cory and Dorkula, your sweet pups and wet pets!
Love the fact that you know show the temp in Celsius as well now for all the non US folk!!!
Love my ghost. Thanks for the info Cory...

can 7 inches black ghost knife fish be combined with 9 inches arowana inside an aquarium tank?

where is the fish now?

For any aquarium, and especially fish like this, it's a good idea to have an electrical grounding probe.
I was wondering about that
Another tip I have found is don’t keep them with long finned fish. They kinda go into a feeding frenzy at feed time and may mistakenly bite the fins of some fish. Mine would often do this to my Angels, so I had to move him to a another tank.
Hey Cory
Please keep the content coming
Please , we're dying for it 😭😂
Great care tips Cory. In my freshwater days I’ve had a couple of them that got to a pretty decent size. 😊
Neat fish, may try it out one day. Glad I saw this video first. Got some good info and what to be prepared for.
Saw a tru of knife fish on display at my bigger lfs. Had never seen them in real life before but instantly recognized them as those little “knifes”. Would love to have one one day.
just got my first gk and I'm in ❤ small and friendly so far🎉 and yes i want more now!

Hopefully you upgraded. They get long.
I’ve allways wanted to get a black ghost, thanks for the vids Cory, and the amazing store products.
I've always liked to pull up a chair and watch these guys.
🤶Happy Holidays🎅
Merry Christmas, Cory and all the fish nerms out there!
I liked that you put the temperature in C°
They are fun. Mine used to love being hand fed
Such a cool fish just getting into the hobby trying to set up a planted tank.
Great run down on this fish!! How interesting and I don't know if I've got the skills to keep one or not but it's something I definitely would love to consider! One of my dream fish for sure! Thanks Cory for all the information you provide! I hope you and your family are having a happy holidays!!🙏😍🌿🐟🎄🌿💚
Mine is pretty large now and it loves the Hikari carnivore sinking pellets. As well as Tetra bits.
What size of tank do you keep him/her?
My two always come out, they are sooo beautiful, in about to get a 6x2 tank and get a elephant nose
I know this is a little bit old but ghost knives and elephantnose et al, do not have sonar
They have active electrolocation and they do not disrupt each other when they are in proximity due to what is known as an jamming avoidance response, where one fish will lower the frequency of its field and the other will raise it, though I am not sure that this works across different species (ie an elephantnose and a ghost knife)

I just ordered the Co-Op mug. I’m excited lol.
Thanks, I have one
Getting a big tank soon hopefully
even tho this video is two years old. it still helps a lot
Very timely video for me. Thanks!
Just got one and he is awesome! This video really helped round out my questions!
ah man this topic was my most viewed video topic on my page lol guess i’ll drop down a few pegs on the first search results now 😂
Merry christmas cory and the co-op family. Thanks for all you do.
African brown knifes are good too
They look like a fun fish. Maybe one day. Thank you 😊 Take care
Thanks for your knowledge! Have a good one

They need 75-125 gallons at minimum.
I was just thinking how you said you’ve kept these, then you put a video out on them haha. Didn’t you keep one with ladybird at one point?
If they're big enough, they'll eat a cube of tubifex worms in one bite. My big boy recently passed away when I set up a new tank ;( But I got a new baby black ghost knife fish, he's doing great!
