This is Darby. He is a pretty cool fish. Sometimes he just goes crazy for no reason and gets all puffed up and big, looks like he wants to kick some body's ass, I guess that's why he is kinda named after Darby Crash, the singer of the late 70's punk band The Germs. Darby Crash died of a drug overdose in 1980. He was known for slashing his skin with razor blades on stage and blood would be flying all over the kids in the front row, so punk.
