I have a 25 gallon tank with a clownfish and a damsel as well as a Xenia and a couple feather dusters. There are about 20 lbs of live rock in the system and I was looking to add a cleaner shrimp. I am looking for a shrimp that is easy to care for and non-carnivorous. Hand feeding isn't really an option everyday for me so I'm looking for one that requires very little an is compatible with the creatures in my tank. Any suggestions?
