I have a male halfmoon betta in a 2 gallon critter keeper. He has a cave, some plants (java fern), some fake plants at the surface, and a heater. The highest temp I've been able to get the water to is 78.
He's turning into a serious tail biter. He has beautiful fins, but they're getting ragged. I'm not sure what to do.
I have a 10 gallon tank that's been set up for a year that has 1 male platy and 4 cory catfish. I know the catfish will be fine, but I'm a little nervous about the male platy. I used to have a school of neon tetras in there, but the pH is a little high for them and they all died.
Should I move my betta into the 10 gallon for a while to see if he does better? It's filtered, cycled, heated to 78, and has a light on the top (currently my betta is mostly in the dark, depending on how bright the sun shines through).
