Hello People,

I just got one electric orange hermit crab (calcinus sp) because i needed more help with the tank cleanup...especially the substrate and some green algae on the live rock.

But i understand they need to be provided empty shells so that they dont attack my snail for its shell, so i got some empty shells.

I want to know if i should introduce the shells directly into my tank or is there a particular type of treatment i need to put them through before.
