Ok so it seems to be fungus. I put 1 tbsp per 2 gallons of aquarium salt in my tank last night.DJRansome said:Yes you should be concerned. I can't see it clearly to decide what it is. Google columnaris and see if it looks like your fish. Is it fuzzy at all?
Ok so i looked up what you told me to and nothing on my fish looked like what you said you thougjt it looked like except fungus/fin rot.DJRansome said:Columnaris is not fungus. Paraguard will not fix fungus. Not sure salt will fix fungus either.
