Does anybody know of a good number of emralds for a 50 gallon? Also, is there any other crab that won't specifcally target my snails? Thanks for the help.
Well just saying that you might want to consider first if theres enough algae for him or her to eat and if its mature enough for the tank to create enough algae to satisfy the emeralds
My zebra hermits have never bothered my snails. I throw in extra shells just in case they feel the need to change, I have one that changes all the time.
