One of my favorites I would like to add to my future aquariums! I truly like the Black variety with their blue eyes! Great species spotlight! Thank you so much for sharing! 👍🌱🐟🌿♥️🙏
The black emperor tetras are really nice. A little tip regarding their 2 different eye colors...the males have the metallic blue while the females have the metallic green eyes :)
Great video Blake, they certainly look like a stunning tetra to have in any aquarium, love the setup with the betta and the live plants, keep up the amazing work mate
I came here to say this, there are 2 different species of "emperor" featured in his video. Impachthys species do not have the tail fin extensions, nematobrycon do.
I find these to be the most confused fish I have found in the hobby. The Royal Tetra is Inpaichthys kerri where as the Emperor Tetra is Nematobrycon palmeri. Videos like this only add to the confusion.
I'm in the planning stages of a 250usg community tank. I'm really wanting to highlight one particular fish. It will be fully planted and the water where I'll be living is quite hard and ph around 7.9. Yes I'll have lot's of corys, probably fairy corys and some loaches, such the true golden zebra loach. Emperors are great, but the water isn't suitable. What are some fish you'd consider in a school of say 60 or so, in a tank that size?
Hey Blake! Great video and beautiful fish! Would the emperor tetras do well in a moderate/high flow river style tank? Or do they only do well in slow water?
Ok thanks Blake! Maybe not the right setup for them. The tank is a riverstyle with stiphodon gobies and a panda garra. I’m looking for a top dweller (other than WCM) that will stay up top/middle and not eat the goby’s food on the bottom bc they are such slow eaters. But maybe that is not possible 😂😢 Any other fun alternatives?
Nice video, I'm planning to incorperate five Emperors with a group of seven Zebra Danios and a few assorted live plants. Do you think that would work out well in a twenty gallon? Thank you
Hi, you mixed up 2 different species. The emperor tetra, which is bigger, can come in a black variety, has no adipose fin, and can be sexed by the eye color and fin extension. The king tetra, which is smaller, can come in a super blue variety, has adipose fin, and can be sexed by the color of the adipose fin. Best regards
@@BlakesAquatics hi, I am sorry, i am not referring to the accent. The fish on the video cover, as well as the black one or the ones at 3:28 or 1:53 are palmeri, not kerri. The kerri are the ones at 3:14 and 4:15 You can recognize it easily because the kerri has a small fin between the dorsal and the caudal, while the palmeri does not
Neither are called king tetras, king tetras are also known as cochu tetras. In Aus, palmeri and kerri are sold as emperor tetras, the video is on emperor tetras, and a lot of people would buy either version from a retailer under the description emperor tetra (black) or emperor tetra. Agreed though I should have referenced kerri AND palmeri
@@BlakesAquatics In the US, the palmeri are called emperor tetras while the kerri get an annoyingly varied qualifier (blue emperor, purple emperor, royal emperor, regal emperor, kerri emperor) or are just called Kerri tetras. And yea, there are some who call them "king" tetras, but that seems to have been started by those who called them emperor tetras in the beginning before learning there already was an emperor, so they made something up (they thought). If you want to go back and tell them there's already a king tetras too, I'd love to see their faces! 😁
This guy is confused. He has two species from different genus and is confusing them for the same type of fish. One of the fish featured in the video is most commonly named the Emperor Tetra, specifically Nematobrycon palmeri. Also in featured this video is what is most commonly named the Royal Tetra, specifically Inpaichthys kerri.
That is true of the Emperor Tetras (Nematobrycon palmeri) in this video. Also the males have a trident tale. Just to be clear there are two different species of fish being portrayed as the same species in this video. The Royal Tetras (Inpaichthys kerri) do not have blue or green eyes nor trident tails. These two species are commonly confused throughout the hobby.

Looooooooved this care video! they look beautiful and seem to be such an under rated fish!
Perfect timing on this vid! Just purched a dozen black emporers. Look smicko in the tank. My new fave tetra!

Never had these in any tank in the past, but I always wanted them. Might have to give them a go this time around.
The black ones and the one in the title photo aren’t Kerri’s, just Emperor Tetras (Nematobrycon palmeri)

Absolutely stunning fish! Thank you for sharing!!
Stunning thumbnail 🙂🙂
I've got a number of these fish myself. 👍
Thanks mate yeah i love them

Maybe some pseudomugils? Swordtails, congo tetras, columbian tetras maybe
@@BlakesAquatics oh I love the idea of a big school of congos.. thank you
Hi Blake, great video, just some extra info, those with blue eyes are males and green eyes are females.
Thanks for that, I wasnt sure but did wonder if that was an idicator of gender. 👍👏
@@BlakesAquatics also the fin extension on the tail fin, the females don't have it. The eyes are a sure fire way of telling though.
Hey Blake! Great video and beautiful fish! Would the emperor tetras do well in a moderate/high flow river style tank? Or do they only do well in slow water?
Moderate would be fine id say but they dont really want a hillstream kind of effect
Ok thanks Blake! Maybe not the right setup for them. The tank is a riverstyle with stiphodon gobies and a panda garra.

Very cool fish, great info as always
These fish are surprisingly beautiful. Especially the males.
Underrated fish imo 💜
Nice video, I'm planning to incorperate five Emperors with a group of seven Zebra Danios and a few assorted live plants. Do you think that would work out well in a twenty gallon? Thank you
Yeah i reckon that would work fine
I have a 42 gal tank. What would be a good amount? (I don't have any other fish inside)
25 or 30 if you want instant impact
The Royal is the strongest to me, very resistant
I've recently purchased the super blues, I was wondering how you can sexe them? they all look the same
Fin length and slenderness
Just got 15 to pair with my angelfish and scissortails rasboras in the 65 🙌🏼
great choice!
Hi, you mixed up 2 different species.
The emperor tetra, which is bigger, can come in a black variety, has no adipose fin, and can be sexed by the eye color and fin extension.
The king tetra, which is smaller, can come in a super blue variety, has adipose fin, and can be sexed by the color of the adipose fin.
Best regards
Hey, i keep king tetras as well. Maybe my accent meant you were confusing me saying 'kerri' with king?
@@BlakesAquatics hi, I am sorry, i am not referring to the accent.
The fish on the video cover, as well as the black one or the ones at 3:28 or 1:53 are palmeri, not kerri.
The kerri are the ones at 3:14 and 4:15
You can recognize it easily because the kerri has a small fin between the dorsal and the caudal, while the palmeri does not
@@BlakesAquatics nothing bad in having them in the same tank, but if you are talking about kerri and show pics or clips of palmeri, it gets confusing

Just got 6 of these :) we dither fish for my plecos
Can I put 10 in a empty 20gal just themselves
yes I reckon that would be fine.
Thanks for the info! Greetings from Israel :-)
Welcome!
What do you think of blue cochu tetra colors?
Stunning
Love these guys. But my blue tetras are mean :(
Wait... I thought they're a part of Nematobrycon?

Ive read that the green and blue eye colour difference is their gender traits
Yes i agree now
شكرا
nice
Thanks
They look cool, still a tetra though.
Hahaha one day well find you a tetra you like
what's wrong with tetras? They are fuking stunning
The black ones are in a completely different genus: Nematobrycon.
Yeah thats my mistake, i thought they were just a colour morph until releasing this video
Kerri tetra is another species than emperor tetras
My mistake, you are right
First
Blue eyes are adult males, green eyes adult females.
That is true of the Emperor Tetras (Nematobrycon palmeri) in this video. Also the males have a trident tale.
Just to be clear there are two different species of fish being portrayed as the same species in this video.
The Royal Tetras (Inpaichthys kerri) do not have blue or green eyes nor trident tails.
These two species are commonly confused throughout the hobby.
2 different species here. Your black one's with blue eye are a black version of Nematobrycon palmeri, the Emperor Tetra, not the Kerri Tetra
Yeah thanks for the correction, realised months later because of comments like yours 🤦♂️
