I've had goldfish before, but this is something new I'm seeing. I usually get a couple black moors to put in with the goldfish when I have a goldfish tank going. The black one was purchased at the same time and place as most of the regular goldfish. The black moor seems to be a bully though. He (she) chases the other goldfish and nips at their rear-ends and back fins. One of the biggest draws of a goldfish tank, for me, is how peaceful and calming they are. I have to admit, it grates on me to see the goldfish getting bullied. I've seriously considered just scoopin the lil bugger out of there and flushing it, but figured I'd come here and find out what I could first.
