Right after I posted I decided against it just based on the fact I like the way the tank is set up and the cray likes to ruin everything I try to set up in his/her tank,sob. But the tank hes in now, this is crazy I know, is where I keep ghost shrimp and breed feeder guppies to feed to the bushfish. ive seen ghost shrimp on top of him. I read they were aggressive but mine is mellow. I saw him trying to get a couple rosey reds but he did not put in much effort. wouldnt want to risk the bushfish either, love that little guy.
