I went to check on my betta, Pontus Rex, after work today and found him with shredded fins! I had him in a 2.5 gallon tank, but I didn't run the filter because he didn't seem to like the current. After a while, I noticed the top of the water would have a murky scum from being stagnant. Also, his fins have looked a bit crumpled and folded over on top (I check on that earlier, it wasn't fin rot, just an aesthetic issue). I decided this past weekend to start running the filter, hoping he would just adjust, and also to start using Stress Coat as a water conditioner, since it has such a great reputation. I was really hoping that his would clear up his previous fin issue and just improve his overall health.
I go to check on him after work today, and see that the top half of his fins look like they've been run across a cheese grater! Why is that happening? Could he have been sucked into the filter? Could he be tail biting because he does not like the filter? What are your recommendations to stop and fix this fin problem?
