Well not sure what is going on with one of my female mollies ... she is very fat and sticking to the bottom. Mouth is constantly going as if trying to take in more water. Thought maybe PG but that doesn't seem to be the case. Not sure if she is constipated or not. Haven't really seen her poo either (but I don't really sit and wait for it). When it's feeding time, she's the first to swim to top! No other signs. Any advice would be greatly appreciated.
. Water parameters are great. Water is clear.
