(( I hate that my first post is an emergency post I but hi ))
My super delta betta McGee has many tears in his fins (primarily caudal) that don't get better. There aren't any signs of infection and is definitely not fin rot. He's had them for too long and they don't get worse or better. I've done the usual of upping the temp and adding salt but have gotten no results. The filter is kept on the lowest setting and doesn't push him around. All decorations have no sharp edges. It just odd!
He's kept in a 6.6 gallon long/book shelf aquarium kept at 77-80 degrees. It is planted ( 3 anubias plants, 1 java fern, and 1 marimo ) and he is kept with two African dwarf frogs. The frogs aren't responsible seeing as I haven't had them long and the fin problems have been going on for weeks. He used to be kept in a 2.5 gal before this one. Other than the tears he eats fine and has normal behavior. He is a low aggression betta so it isn't caused by fin flaring seeing as he rarely does it. Any ideas why they won't heal?
