So I finally got myself a mantis (Emerald) and have put the cirtter in it's new home (5 gallon). He seems to be loving it b/c he's just running around all over the rock and tank. I was wondering how often I should feed him live food. I have some ghost shrimp and fed him one today and he tore it up. I have heard to feed them live food once per week and then substitute with frozen food the other days. Would frozen mysis be a fine substitute? Any suggestions would greatly be appreciated!!
