My betta Tully is a notorious tail-bitter, but his fins look much worse today. I moved him and my other betta into my dorm room on Thursday and have been staying up late to organize things. I'm hoping that this new fin damage is just because he's upset about the transition and the light.
**Also, I just checked the parameters and actually have ammonia and nitrates for the first time, which I guess means that his tank is beginning to cycle. Could that be what is bothering him? Based on the readings below, what type of water changes should I start doing?
Do you think these pictures indicate fin rot or tail-biting? His caudal fin normally looks frayed like that, but his dorsal fin looks pretty messed up. I don't notice black at the edges, which gives me some hope that this is just tail-biting.
