Hey so I just had my madagascar rainbowfish die today from as far as i can tell a parasite... all of the other fish seemed fine however I am noticing a few fish (particularly my balloon belly mollies) rubbing up against decorations and I saw one do it one time on the gravel... cant see anything like ich but other parasites are a possibility. Does anyone know what it may be and potential solutions? I think I will turn my heater up to 85 or so tonight jic...
