Hello, My fish's tails are shredded. I don't know why. I am pretty sure it's not finrot since I just got him yesterday and cleaned his tank. I am wondering if he may have gotten sucked into the filter and got his tails shredded. :(
Also there is another issue: my fish is being overly agressive. It saw it's reflection in the tank today and flared up and started to swim around in a huff which was pretty funny. But then it just started to stare at it's reflection for hours. It even headbutted it's reflection twice! I am worried that this may cause problems for his health. I know it's normal for betta fish to be agressive but he seems positively enraged!
