I've never seen them but its worth a try, I'm getting sick of them dwindling away one by one. I'm wondering if its nudis though as they're so slow to diminish. You'd think with all that food in there for them the population would go nuts and they'd be going to town on the zoos. Unless of course they're picky and like the colored/expensive ones, there's only about 2 of those left so if they plan on staying alive they're going to have to be less particular
