I've named him Cthulhu. He's a spotted piranha. I haven't been able to take pictures of him. He's still hiding. When we tried to bag him at the store he bit through the first bag! On the second try we triple bagged him, put a brown paper sac around the bag, and the lfs
guys gave him some sort of fish sedative. Ever since I got him home he's just been hiding under some drift wood. Must be hung over....
