Aguinaga Posted October 3, 2023 Share Posted October 3, 2023 I picked up a 240 gallon tank Saturday. It came with a handle full of fish and I know the peacocks but these guys I don’t have a clue. Any help would be greatly appreciated. Link to comment Share on other sites More sharing options...
mynameisnobody Posted October 3, 2023 Share Posted October 3, 2023 (edited) Not too sure on the top fish, but the second photo is a ripsaw catfish also known as a Niger cat, and the last appears to be a six banded distichodus. Beautiful fish, be very careful when having your hand/arm near the ripsaw. Their sides will slice you open and they get laaaaarge, approx 36”-39”.

Aguinaga Posted October 3, 2023 Author Share Posted October 3, 2023 That you @mynameisnobody kinda surprised he got it such a river monster in the mix. Seems strange to have in with these guys 1 Link to comment Share on other sites More sharing options...
Colu Posted October 3, 2023 Share Posted October 3, 2023 (edited) The top one looks very similar to an electric Catfish @Aguinaga @mynameisnobody Edited October 3, 2023 by Colu 1 Link to comment Share on other sites More sharing options...

My mind would never have gone there. They get to 3 feet long depending on species! Link to comment Share on other sites More sharing options...
mynameisnobody Posted October 3, 2023 Share Posted October 3, 2023 @Aguinaga It doesn’t surprise me that a river monster was added. People still buy pacu’s and those shouldn’t be sold in the pet trade. From the variety I seen in that aquarium, it doesn’t seem like the previous owner cared much about future planning, seems like they were added until something goes very wrong. @Colu Nailed it, great job. 1 Link to comment Share on other sites More sharing options...
Colu Posted October 3, 2023 Share Posted October 3, 2023 Looking at the bottom picture it looks more like a banded leporinus than distichous to me @mynameisnobody 1 Link to comment Share on other sites More sharing options...
mynameisnobody Posted October 3, 2023 Share Posted October 3, 2023 @Colu Could be, but the red in the fins led me towards the distichodus. I was thinking leporinus at first as well, but that red stands out. 1 Link to comment Share on other sites More sharing options...

The one in the background look more like a leporinus could be two different species in the same picture or it might just be my eyes playing tricks on me 1 Link to comment Share on other sites More sharing options...
mynameisnobody Posted October 3, 2023 Share Posted October 3, 2023 @Colu it very well could be, honestly with this variety of fish, it could also be a piranha. 1 Link to comment Share on other sites More sharing options...
Biotope Biologist Posted October 3, 2023 Share Posted October 3, 2023 I agree with @Colu on all identifications. Top: African Electric Catfish Middle: previously identified as a Niger Cat Bottom: Banded Leporinus Leporinus species tend to develop red/orange/yellow in the fins and body as they age Its not surprising to me that they kept very large fish in with the African cichlids. If kept these catfish will eat the cichlids once they get large enough. And despite large African Cats being sit-wait predators I still recommend they go in no less than 500 gallons of water. Monster fish are often the most neglected as they are not feasible pets for 99% of fish owners 1 Link to comment Share on other sites More sharing options...
mynameisnobody Posted October 3, 2023 Share Posted October 3, 2023 @Biotope Biologist If you use the small sponge filter for size perspective, it isn’t a very large specimen. I’ve found no photo evidence of red in the leporinus fins. However even from a small size: I could be wrong but I’ve seen both species as babies and full size in person and the banded leporinus always had translucent fins. I’m going to see what the folks over at MFK have to say. Link to comment Share on other sites More sharing options...

I’m going to see what the folks over at MFK have to say. I could very well be wrong too! Despite them being from very different continents, both species have the same fin position and even an adipose fin which is often used to narrow species down in my field as it’s rather uncommon. Im using the very unscientific instinct here. Don’t tell my coworkers but I use this more often than I probably ought to.

mynameisnobody Posted October 3, 2023 Share Posted October 3, 2023 @Biotope Biologist I totally get it, we’re all playing detective. It’s kind of fascinating when the smallest feature can differentiate between species. PS I am rather envious of your line of work. 1 Link to comment Share on other sites More sharing options...
mynameisnobody Posted October 3, 2023 Share Posted October 3, 2023 Apparently I got 4 different answers to the identification. It may remain a mystery. Link to comment Share on other sites More sharing options...
Aguinaga Posted October 3, 2023 Author Share Posted October 3, 2023 This is awesome. Really helps out guys. I get off work and it’s like a story book to read. It’s respectful, knowledgeable, and funny. Can’t ask for better help. 2 Link to comment Share on other sites More sharing options...
