I had my first pleco for almost 4 years before he randomly died, and all I could find of him was his skull. (Tank parameters were good) I just got a new pleco a month ago, and he had been doing really well. I fed everyone yesterday, and he was attached to one of the plants. Then this morning I went to check on him, and all I could find was his skull. Just based on how she looks this morning, I think I know which fish did it, but I’ve had her for 6 years with no other issues. Has anyone else had this kind of problem with goldfish? I like having plecos, but I don’t want them to keep getting eaten. Should I try a larger size pleco? My tank is 75 gallon with 4 goldfish.
