Hi, based on some respond to my previous post either a have columnaris and/or fungus in my tank (white fussy cotton like appearance, pic attach). Recommendation for it is Maracyn. Now, is Maracyn ok for prego fish? I'm pretty sure affected molly is prego and I don't want for the frys to be affected or get killed. I'm thinking about putting the infected fish in a 10g tank, do I need to put something specific in it? How about temperature, my tank is around 80's all the time do to the fact that I live in Puerto Rico and is always hot and humid, tank is place where it receive some of day light but I have curtains and sun is not direct, but still temp is always around that and fishes never complain, it concern me in case temp had something to do with proper treatment. Please anything always welcome!
