Why is my frogs stomach like this?
He's always had a flatter belly, and lately he's been hanging by the heater at the top of the tank all day. The temp stays around 76°F all day, I have the thermometer set up on the opposite corner so I know how cold it can get. Its probably warmer next to the heater.
He didn't eat on Monday... I think the last he ate was last Thursday (I feed Mondays and Thursdays w/ brine shrimp), and recently his tank mate died whom I adopted when she had obvious bloat... It's my first time with an aquarium, I'm struggling a lot and I just can't handle my good buddy passing if it's something I can treat. He's been to the vet after his tank mate died and was prescribed antibiotics just in case, which I did the full round of.
I have a lot more questions but I also am embarrassed for rambling.
