Always hungry acans?

[ngvu1]

I have this rainbow 3 head acans frag and they all dead, the baby heads came out shortly after and I have been feeding them with coral fenzy and Fauna marine LPS and they multiply at an OK rate but their tentacles are kind of always out every time I look at them

They look like this when being squirted at or not happy

This guy I recently got and they don't show their tentacles like my rainbow
