Ok so my mother in law has a tank that I take care of...this morning when I went to feed them I noticed a problem with one of the fish. It is a African cichlid and normally looks like this: Now looks like this: He's been upside down now breathing for over 12 hours. I found him around 8am this morning and it's now 8:20 pm... I have him quarantined I'm a 10gal tank and have added melafix to the tank to see if it would do anything....any help is appreciated!!
