Then I would try first a fish... 50% chances that he will eat them. Other people buy fire shrimps but not sure if they will eat the Mojano, I know they eat aptasia. But it's a 50% chances too... This is all "natural way"
There's a lot of chemicals out there but I can't recommend any... or you can try THE LASER that someone put a threat on this forum!!! that's nice and fun!!! LOL but expensive.... but never tried it myself.
Good luck!
