I had tried 3 different times to purchase a Cleaner shrimp for my 30 gal tank with Eclipse 2 hood. 2 different LFS and every time the shrimp barely makes it out of the bag. He swims out after being aclimated and after a few minutes he is on top on the live rock and walking and then soon after...they fall over on their sides and become motionless. I have a coral banded shrimp in the tank and he is fine. No creatures go near the cleaner at anytime while he is alive. I had my water checked...no problems...and I heard that cleaner shrimp are hardy. Can anyone advise any tips? Thanks in advance! -Bobby
