I have had this Betta for roughly a month, and have noticed some ripping/fraying around his caudal fin, and some on his dorsal. Currently I'm doing a 50% water change every 2-3 days to try keep it clean so he can heal. I also removed a sharp decoration, though this morning he had a new rip in them. I'm currently unsure of what to do - should I treat for finrot? Should I remove remaining decorations (a ceramic hide and a plastic plant, I can't remove the anubias he has - could the gravel be an issue?)
There's no need to remove the live plant. Esha 2000 is a three-day course so shouldn't affect water changes if you're doing a typical 25% once a week. Just make sure that after the first dose you don't do a water change until day four.
Ah alright, thanks for your help. Right now I've been doing 50% every 3 days to help keep it clean for him. Im just looking for where could sell some because i don't want to wait delivery times. Is there a way i can prevent this in the future?
For prevention, improved water quality through the more frequent and larger water changes such as you're doing should help; if the problem is recurring, then it's possible that he's catching his tail in decor or that something (eg noise, his own reflection especially if the room is dark and his tank is lit, boredom) is triggering him to bite his own tail - keep an eye out to see if any of these might be the case and address accordingly.
