Problem with Red Parrot Cichlid
So I did someone a favor and took in his last 2 fish, a 10 year old red parrot cichlid and a 5 year old convict. The convict went to the BAS auction before he killed off all my fish and I still have bpc. The problem is she started swimming with her head down, looks like she's doing a headstand. Some blood parrot people told me it's swim bladder and to give her shelled peas. She won't eat them...someone else said possible parasites. Does anyone have any idea why she would be doing this? I got back into the hobby 5 years ago and in all 3 tanks I've never had any illness...algae yes, illness no. All the other fish are fine. If it is parasites should I treat the whole tank? What do you all think this is?
