as long as they aren't in the main tank with the fish
He is. As long as he's well fed, there shouldn't be a problem. Just bought another 100 snails for that purpose. Only have a Lawn Mower, YT, Purple fire fish, and 2 lyretails, no problems yet. Only been in the tank for mos though. Time will tell.
I just like that whole natural reef approach, macros in display, predator prey kinda thing. i obviously don't want him to eat any fish, but if he does, I buy a bigger fish.
He's actually crawled onto my hand! 8O
