Hi
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.

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??
Cheers

Looks like lymphocystis. Viral and mostly cosmetic. Think human cold sore. Will not be cured, but in a healthy fish, can be kept in remission. I lost a rainbow to this, but I think she had other problems. Google and read up a bit more about it.
