Very cool! Has anyone done a necropsy to examine the digestive contents of wild specimens? I'm fascinated by that information with mid sized fish. Thank you for sharing
@belowwater do you happen to know which university, collection areas or fish are being studied this way by chance? I've been very curious and doing research on the gut flora and fauna of fish... everything from yeast, archaea, bacteria, to auwfuchs, biofilms and the things we traditionally think of as " food ". It is amazing how often parasites, or symbiotic species are found in wild fish and yet in captivity we clean out their gut biome and feed supposed super foods, only to find the fish are malnourished or ill. I'm always curious with algae eaters or sand sifters, what it is they target vs what is ingested due to proximity with the desired prey on the menu... micro crustaceans and algae are often both found but in new tests on plecos, they found that they did not eat uncycled/sterilized algae... but readily ate "cycled" algae... and skipped algae all together if the crustaceans were separated out as well.
@@Fishtory if you search by diet or isotope analysis you should find plenty of papers - there are of course tons of studies on the big food fish such as salmonids, and tropical aquaculture species but there are also some on reef fishes, Amazonian species and Lake Malawi fish. In the case of these sand sifters, they ingest a lot of the bacterial mass that holds debris together on top of the substrate, i think there are some nutritional studies done on that as well.
Another captivating video!!! Thank-you!!! I smiled the whole way through, while thinking 'WOW!' through each new school of fish to pass in front of the camera. I am so very glad that you share this underwater part of your life with us!!!
You have no idea how valuable your videos are. I am into fish keeping and always try to provide a habitat very close to their natural habitat and your videos are simply priceless. Would you able to assist me with few queries I have regarding Suriname river plants and schooling fish
@@belowwater there’s a weird plant growing where the water of my DIY filter runs it’s still small but I’m wondering what it will look like in a couple of months
Your videos are so informative and beautiful to watch. You're doing a great educational work, I appreciate it as a fish keeper. I truly hope we can preserve all these ecosystems.
thank you. this is one of the most remote places i have seen, I think it is reasonably safe, unlike northern Suriname that is under huge pressure from logging, mining and industrial agriculture.
Very cool. I had some Suriname Red Spot Cichlid (Guianacara sphenozona 'red spot') and still regret having to rehome them. I love your educational videos. Thanks
Please make a atleast one video on where and how these fish lives at night Ive never seen any night footage of these fish So curious to know these fish forage in dark night
All cichlids, characins just sleep, either directly on the bottom or in rock crevices etc. At night other fish are moving, fish you don't see during the day like Doradidae, Auchenipteridae and many electric fish.
@belowwater don't they hit any obstacles wood or rock I mean when there is flow water current And then how they stay together Really curious to see that
@@yashtapase3821 same as in your aquarium, the fish find quiet places and don't move unless something tries to eat them. Will eventually show something with all the knife fish at night, it is difficult to put that together where it still looks interesting, but with the new cameras it will film more easily.
it's a riverweed plant (the family is Podostomaceae), but I am uncertain what species it is. _Mourera fluviatlis_ is kind of similar or this could be it, riverweed plants have many different type of leaf structures depending what growing stage they are in, and during the dry season they only exist as seeds...very tricky.
My LFS had just given me some bandit cichlid fry and I was looking around your videos for footage of them in the wild. Mine do look slightly different though (no black on middle dorsal for example), I was wondering if it's a different collection point or breeding that causes this. Timing couldn't have been better and fantastic video as always!
There are 7 _Guianacara_ species across Venezuela-Guyana-Suriname-French Guyana, plus undescribed ones in the Tapanahony in Suriname, and in the Rio Jatapu, Brazil.
Great video as always. The Suriname nature is breathtaking and let’s hope the gold miners and oil companies stay away from this region in the south. The destruction is so depressing. Your videos are wonderful though.
the big fish usually occur in water that is not so clear or very deep, and even then likely stay away from something as large as them. Biggest i have seen is P.brachyura. That fish is the same size i am with fins: th-cam.com/video/7BjRNKJkvPs/w-d-xo.html
Suriname is where i got hooked on fish when i was a lil boy.
Imagine just spending the whole day exploring in that river 😉

Yes, there is some work done with isotopes and with gut content of various cichlids in other habitats.

sure/ the upland has not many plants other than Podostomaceae (River weeds), which should be near impossible to grow in an aquarium

Absolutely wonderful to see footage of my beloved Guianacara in the wild. Thanks for this :)
glad you like it, they are such nice cichlids!
Great video!
Wonderful images! Very interesting. Thanks for sharing from France 🙂
Merci!
Beautiful footage as always.
Awesome thanks for sharing
Many thanks for sharing, Oliver! Greets from Germany.😊
Many thanks!
Awesome vid as usual 👌

What a amazing video thanks for sharing
Thanks for visiting
was es noch so alles an tollen fische in der natur gibt, die man in einer zoohandlung so nie sieht...😉👍👍👍
ja, leider - in Nordamerika wird das Sortiment auch immer geringer.
@@belowwater danke für deine antwort...😉
Very cool. I had some Suriname Red Spot Cichlid (Guianacara sphenozona 'red spot') and still regret having to rehome them. I love your educational videos. Thanks
yes, they are really fun and not so big.
Wonderful footage and commentary Oliver :)
Many thanks!
Awesome 👌🏿 👏🏾 👍🏿
Thanks
🌴Another Awesome and Enjoyable video, Thanks!!! 🌴
Its so sad all the destruction and fires going on all through South America....😪😪😪
OH OH OH 10/10 I have some
wow awesome, more
Thank you, I will
very interesting, thanks!
Good job!
Wonderful! These fish are so cute and nice to watch
yes, they have all the fun quality of ramirezi except the colour!
Your content is amazing!!!
Thank you so much!!
Amazing and inspiring video! Thank you Oliver!
thank you!
Very interesting
Amazing
Thanks for sharing this video I’m a local Fish keeper from Suriname 🇸🇷
Thanks for watching!
Great video including a geophagus that was new to me.
it's one of my favourite Geos, but also big, and i think the most difficult to keep.
Stunning video 😍🙏 what was the tiger looking fish @7:08? Leporinus?
thank you, yes, the real _Leporinus maculatus_ - that name gets used a lot, but this is the actual one
I absolutely love your videos.
Thank you so much!

We'll wait for that video

Do you never swim into huge man size predatory fish
