Hi my name is Danielle and this is my first post here unfortunately. My husband and I have a red sea 34 gallon. Set up for a few months cycled with live rock and waited until water perimeters were good before adding fish. We added had 2 clownfish to start and then added 3 yellow tailed damsels . They were thriving until we added 2 snails and a cleaner shrimp and suddenly were loosing fish at an alarming rate. This is our second last damsels and I'm certain he's on his way out . Just wondering if anyone knows what this might be and if I can save the poor guy.
