I had a disaster in my tank a few weeks ago when the heater failed, to cut off at set temp I lost 26 fish, a few survived including my beloved. Spot, ( sorry to sound soppy but I really do love this fish). He was quiet for about a week, but has picked up a bit but now he is moving around I have seen his belly is so sunken, he is getting food as I feed the others that survived (not Plecos) at one end and him the other. I would love to tell you what he is but it’s long been a debate he is similar to a snowball but much smaller and more yellow ( cream) and black he never grew past 3 inc despite a 450ltr tank . Any advice or help welcomed I do not want to loose him
