I was a new betta owner, and new fish keeper, as of last Tuesday. I purchased a beautiful little guy and gave him his own 10 gallon, filtered, heated cycled aquarium (took 6 weeks to cycle) with plants, one of those floating betta logs, and Mopani driftwood. The first night, a portion of his fin ripped getting him into the aquarium but it didn't seem to bother him as he was very active. He seemed so, so happy for the first few days and then on Friday night I found him on the substrate struggling to breathe with most of his fins ripped off. I have attached a picture of his body that will hopefully give you an idea. He died before morning. I have thoroughly searched the tank and I can't find anywhere that he might have torn his fins. I did the pantyhose test on everything I put in the tank.
I'm guessing/hoping that this was just an accident and if I get another betta he will be able to live happily. But since I can't figure out how this guy did this, I am apprehensive about subjecting another fish to this. Any tips or advice?
