Hey guys, just got a new angel fish a couple days ago. Noticed he was getting picked on by a gourami, which he’s gonna be getting out soon. Anyway I took the angel out and put him in a ten gallon with slime coat additive to help his fins grow back. Today I just noticed a sore on his side that I didn’t see before. It almost looks like a callous on our hands, but is on his side. No idea what it could be. Any help would be appreciated. Temp is about 80, no nitrites, ammonia, and nitrates are 10.
