Hello everyone, I’m looking for some help identifying a fish I bought a little while ago and I hope this is the right thread. I believe when I bought the fish the store in which I got it had its scientific name written down on the tank and as you could imagine I cannot remember for the life of me what it was. After some extensive research I found the name of it when I first got it but haven’t been able to find it again. Attaching a picture of it now, it eats and preys upside down, mostly live guppies or frozen shrimp, and usually has the black bar running down the side of its yellow body, but sometimes changes patterns slightly depending on its mood. It’s about 4-5 inches and always uses its dorsal fins to anchor itself to the bottom or a structure in the tank. Thanks in advance!
