Hi there.

so strange not being in the catfish section lol. So i have done a bit of research on short bodied fish in the past. Turns out that when people bred various fish for short body traits no one really understood whay was going on. What is happening inside the fish is the spine curves irregular which effectively shortens the length of the fish but also can give it a slightly lumpy appearance.
So what does this mean for your fish? You say when you bought this fish it looked normal? In this case i do not believe your fish to be a short body in what we usually think of as short bodies. It wasnt this way from birth. Thats a clue. Also the skin appears discolored and irregular. I think you should treat this fish with extreme caution. There is a desiese that can cause a curvature of the spine in fish similar to what you would find in short bodied fish. That is fish TB. Tuberculosis for fish. After researching this you may considering culling that fish. Could be disasterous for anyone who comes in contact with your aquarium water. Especially if they have a weak immune system for any reasin. Not saying that is what your fish has but please be careful and do some research on this. It isnt normal for a fish to develope like this when it was normal to begin with. Good luck.
