Can anyone tell me what's wrong with my betta? I don't know if it's fin rot or something else. I currently have:
- 3 gallon tank with a divider (will be upgrading to a 10 gallon when I move this week)
- a controlled heater
- a filter
- caves for each betta
- a silk plant
Ok, so I'm visiting my friend and she has a Betta fish. I've visited three times since she's gotten the fish. First time: fish looks amazing. Perfect half moon shape, great personality. Second time: grew a little; fins looked curly at edges. Third time: fins still ragged, a few tiny chunks...
