Cleaner shrimp are pretty cool regardless. My Blue tang has had ich twice in the 6 years I had her. I just soaked the pellets in garlic for both times and it worked. She got it at first, and then later on after my incident when I lost all but two of my fish when I added a scopus tang.
I used to put my hands in the tank and watch as the cleaner shrimp pick at my fingers.
i have cleaner shrimp in all my tanks and all 3 have "cleaning stations" and have for over a year seems like they only do it after i introduce new fish or alot of corals but when i do they r cleaning for a week or so dont know if its a reaction from stress or whatever but its cool anyhow lol
I have just a blood shrimp now, and it doesn't behave like the cleaners (it hides under one rock, and it isn't a cleaning station) but it is still pretty cool. I tend to like the inverts anyway.
