I'm not good at managing aggression, and these guys have just about driven me crazy. The biggest one in a group of 10 (from Mark Chen) killed 3 overnight, and I had to separate the remaining 7 into 4 tanks. Finally got them all pellet trained, and I'm slowly putting them back together.
Here is one of the medium ones. Still small but getting some color and attitude.
