Thanks everyone, they certainly are not shy. I can't really even enjoy them swimming around and carrying on since most of the time I am in the room they are at the glass begging.
The black belt is the boss of the tank whenever there is not any breeding going on. I imagine that will change soon though. There are going to be a few monsters so it is kind of hard to tell who is going to be the boss from one day to the next. Suprisingly though there really has not been any real violence. I'm hoping that it continues that way.
Here is another video. The tank seems to be clearing up pretty well. I give the reactor and media full credit.
