I have a 2 year old halfmoon rose tail named moon who just wont quit tailbiting!
He had come down with a case of fin rot after being in a tank with another fish that had septicemia, so I put him in a ~.75 gallon jar (heated) and did a salt treatment on him, unfortunately, he did not like his little bowl, even though there was a little toy for him in there, he started tail biting, so I cleaned out a tank for him (barebottom) and he is now in a filtered heated 10 gallon tank
He has about 3 gallons to himself and then I have a divider that has 3 guppies because i had nowhere else to put them.
But hes still biting his tail!
I have a little fake plant and a cave for him, but he is still biting.
I have been using stress coat+ in the tank as well. I'm not really sure what to do with him because
he is being rehomed soon--and the person I am giving him too doesn't know much about betta and I am worried that, if he gets an infection that something bad will happen.
Here is a picture of his tail, as you can see his tail fin has new growth, but his dorsal and anal fins are pretty torn up :c
