My girlfriend was away for a few days. I got here yesterday and noticed that three of our four sorority females have varying stages of some sort of growth on their head/mouth areas. We immediately jarred them and started treating them, as well as the rest of the tank just in case. They were all completely fine behavior-wise and still the same this morning (they acted like their normal glutton selves and even begged for food). Then, we came back this from grocery shopping this afternoon and found the female who appeared the worst off dead.
Of the two remaining sick ones, one girl just has what seems like the beginning of a receding mouth and the other has a whitish growth that is swelling out of her mouth in front of her eye. We think it is columnaris, but we're not sure. The rest of the fish from the tank look healthy.
Any help would be greatly appreciated. Thank you.
