I have a 75 gallon freshwater tank with fish including a 3.5" leopard ctenopoma, 3" african featherfin catfish and an approximately 4.5" african brown knifefish. I had a single adult platy that was in the tank as well, because it was a survivor from a columnaris infected tank a while back and I have been planning on moving it out eventually. It seemed perfectly fine for a few months, no one bothered it at all and it either kept to itself or hovered around my angelfish. Just recently I realized I haven't seen it in about 4 days and after searching my tank and luring all of the fish out with food, I still cannot find it so I am thinking it must have been eaten by something. There is no way it could have jumped out of the tank as it is completely covered. I really don't think any of the fish I named are large enough to have eaten a 1.5" (I think it was a bit larger) adult platy whole...? Does anyone think it could have been a possibility with any of the three fish I named?
