My fish likes to hide under plastic plants. There were two in his tank and I removed them both now leaving only the two silk plants in there along with his barrel. The problem is since he likes to hide under them, he managed to rip the top of his fin partially off. Part of it is there. I was just talking about taking that plant out when I got back from vacation and low and behold less than 2 hours later he ripped it. I feel horrible. Is there anything I should be doing for him while his top fin grows back? Do I need to give him anything special other than remove those evil plastic plants?
