I was watching my fish in the tank... and Zim floated up against the divider between him and Chance, and Chance was flaring at Zim, then he BIT A CHUNK OF ZIM'S TAIL OFF THROUGH THE DIVIDER!!! I had NO clue that was even possible! It's a HUGE chunk! I would have though Zim was tailbiting, but it's Chance! First he beat up Haze, then he just did this! I have to take him out of the tank, because he's driving me crazy. Grrr >.< He is such a MEAN fish! I guess I'll just have to send him to Michael, or talk my RA into letting me have a 2nd tank. I can't let him torture my other fish.
