I bought 4 rams yesterday, they seem to have settled in quite well and took bloodworm happily this morning... but I just spotted this one doing rather a large poop with a white thing in it.
I've never had to deal with fish parasites before (if that's what it is)
Does this look like a parasite? and if so what's the best treatment?
I don't want to treat them if they dont need treating, I just want to clarify if it's a parasite or not and find out what's the best thing to use if it is.
