We have a baby molly that is a cross between dalmatian and golddust and she had white cotton like poop coming out of her a few days ago. She hasn't been eating as much (today she didn't eat at all) and my hubby just sent me these photos. In the one showing her rear it is big and white. In the one showing a side view she has (I think) lost her fins on the bottom of her body and she is bloated. We fast or fish one day a week. She will rest at the bottom of the tank, her fins still moving, for 15-20 mins them will swim around again. Could this be an internal parasite? Please help, I'm really worried.
