Betta Fish Tail ripping

[Suzophrenic]

Hi all , I’m new today and not familiar Without this site operates I have bought a half crown elephant better fish with a magnificent tail. And have others in different tanks however his beautiful tail is starting to tear should I keep him away from the other tanks or put him in a smaller one it is becoming more damage by the day. Is this because he’s moving freely or because he sometimes attacked his reflection or the image of another fish appreciate your input please there is no other fish in the tank

Disease can cause fin shredding. Have you maintained your tank regularly?

Can post some pictures of the tank and fish? What size tank is he in and is it cycled?

Can you also tell us the levels of ammonia, nitrate, and nitrite?

Excessive flaring can cause the fins to split but they should heal up just fine in a healthy tank. Do you have plastic plants? Plastic plants or other such jagged decor can rip the fins, as can a filter that is too strong for the fish.
