Does anyone have any experience with cuckoo catfish? I visited Petco yesterday in hopes of finding a couple otos to help with an algae problem in my 20L. No luck there, but the sales girl told me a false cuckoo catfish was very similar and would do the trick. I was so taken by how beautiful this little 1” fish was, that I allowed myself to believe the sales person without doing my own research. Having now taken the time to read up, I’m seeing they grow to 4-6” and can be semi aggressive. I’m supposing this guy’s not the best match for my community tank, but just wanted to check other’s experience before returning him. There’s not much online.
