They are awesome! What I like about them so much, is they are right at home in a high flow system such as a sps system. I think you will have no problems keeping a pair. They prefer to eat pods and such like a mandrin, the red bugs seem an after thought with them. I have noticed them eating prepared foods when feeding. I use Reef frenzy. If you have a decent amount of pods around, you should be fine. They are surprising easy to care for. The only thing you must watch for, is a high powered pump close to live rock. They like to climb all over the rock, and they can get sucked in. I have two vortechs at half speed, and a gyre at half speed, and they have no problems avoiding them. I ran into issues when I had the vortecs cranked on full speed, because my tank is tall and narrow, so the pumps were close to the rock work. I lost one this way. I fashioned some plastic 1/8 inch netting around the vortech, and that solved the problem. Hope this helps.
