Hey guys. Hope you can help me out with this one. Ive got a platy that has been on the bottom of the tank for a good 2 weeks now. She will come up for about 5 min or so to eat, but that's it. She spends most if the time on the bottom. I've noticed that when she is swimming, she has to constantly be moving her fins to keep of the bottom. If she stops swimming, she sinks to the bottom. She is just as active as before, but just sinks like a rock. I'm thinking its some sort of swim bladder issue. The tank is ten gallons. It's just her, two other platies and some rcs. The tank has a bunch of plants too. Ive had her for about a year and a half. The tank has been established for over 2 years. Oh and ive attached a pic of her on the sand. Here are the specs.
