Aquarium Advice Freak
My betta (around six months old) has recently developed a white cottony growth on his fins. He is the sole resident of a 10 gallon tank with lots of live plants, a aquaclear filter (with a sock over the input to reduce flow) and a heater. I did a 50% PWC yesterday when I noticed the problem, and also dosed some pimafix, but it seems to be getting worse and has spread to another fin. I have Maroxy, Malachite Green, and aquarium salt from previous problems in another tank, and can remove the plants if necessary. Any advice on which of these medications to use, and in what quantities?
