Finn had a tattered tail last week so I cleaned his tank and added AS and all. I thought maybe it was because of the filter, so I baffled it. All my plants are silk, there's NOTHING in the tank that can rip his fins now, and when I got home today they were once again tattered. It looks like a flag that has been in the wind for a long time. I'm wondering if this is tailbiting?
Also, he's been really agressive lately could this be what they call "blowing out" the tail?
PS. Not sure if the pictures are clear enough. He LOVES taking pictures to show off his fins...unless it's when I want to take a picture...he runs (well swims)...lol
