In the space of a day, Crayola managed to completely destroy his dorsal fin. No, not just destroy it. It's completely GONE. There is a stub that's only about an 1/8th of an inch long left. His caudal fin is in tatters. I noticed a small chunk of his caudal missing today, and then it was in shreds, and then his dorsal fin was literally hanging on by a thread. I went back in my room earlier after watching a movie, and it was completely gone. I wonder if he's gotten stressed from me not being in my room much in the past couple of days. I've been having bad back problems, and I haven't been able to sit in my normal chair. Instead, I've been sitting at the kitchen table. Could he be stressing out from not seeing me as much? I know it wasn't from the decor. He had one of those stump decorations with silk plants coming out of it, and he's had it in his tank for at least a month. I'm just in shock. I've NEVER had a fish who destroyed his fin so much that it was just literally GONE.
