I couldn't pass up on the goby/shrimp pair Michael @ NYaquatic.com was offering so I ordered them (getting on Tuesday). However they are intended for my 24g aquapod which is already home to my much loved skunk cleaner shrimp... I just heard that pistols may kill a cleaner shrimp??? I don't want to risk my cleaner shrimp if this is true, however my only other tank the pair could go into is my 70g where every shrimp/crab I put in turns up dead very shortly after (my 6 line or very large star are suspected) and I wouldn't want my new pistol killed either... ideas? Which is the safer choice or should I be setting up a new 5g for the new goby & pistol?
