I have a few of them in my tank. They are quite active, and not nearly as aggresive as my bluelegs. I think they would be a good addition to your clean up crew as they are contstantly picking at the lr and substrate. I get a kick out them. They like to climb to the highest LR inthe tank and sun themselves under the mh's. At least that is what it looks like. They are also quite hardy.
Yeah, i like them a lot. They are very active and very good scavengers. And a big plus in my experience is that they dont need new shells. I have had ten for a while now, and not one has killed a snail for a new shell.
