    I have a rainbow fish that has 2 white growths. One is on the top of the gill and one is on its side. At first I thought it could be a fungal infection but I'm unsure. It protrudes quite a bit and looks fluffy but any advice would be appreciated.

    A pic would help. Could be fungal or columnaris

    If he tries to scratch it, or if it has a cottony appearance then it is probably fungus. Fungus is more likely to take hold on injured areas, and at a glance I initially thought it resembled an ulcer but there does appear to be some cottony growth

    Columnaris invades muscle tissue and kills it then fungus feeds on the dead tissue as a secondary infection.

    He doesn't seem to be scratching it and is actually one of the most active and is eating well. would you treat for a fungal infection or bacterial? I have bought king british fin rot and fungus and have melafix already. Or should I buy seachem paraguard??
