Hey guys, So one of my fantails, Dot, has recently been stressed and he was loosing his scales. I treated him with some Interpret Anti Internal Bacteria because he was showing some of the signs that the packaging says to treat if the fish shows them. Does that make sense? Anyway, I also added the correct amount of aquarium salt before to treat his stress. Recently he has been doing loads better but every now and then he has a clamped dorsal fin. Just now I have noticed this reddish lump forming sort of under nether his gill. I have never come across this before so I was wondering what your thoughts are on this. I am going to attempt to post some pictures and get more later when my phone is back from the shop.
