I woke up this morning to find little shreds in Asta's tail. He's healthy, and it doesn't look like disease. It looks like something or someone has done it. The water parameters are fine.
I've never had a tail-biting betta before, so I don't know what it looks like. Is this what it looks like?
Is it possible that Amano shrimp will do this if they get hungry? there are two in his tank.
I did find a piece of plastic that had the potential to do it, but it's been in there the whole time Asta has. I'll fix it, but it seems doubtful.
He's in a Spec III. I have craft mesh over the intake grate. He does like to lay on it. I have the water current turned down. Has anyone else with a Spec III seen this kind of minor shredding caused by a mesh-covered intake grate?
