After getting my 40 gal setup with my already established 80 Lbs of live sand and 65 Lbs of live rock, I decided to restock my tank again since my fight with the aiptasia. So I completely took down my tank and added the rock and sand from my 25 gal. It has been setup for about two weeks so far. I bought an Alardii clownfish today and a cleaner wrasse. Both were doing fine and eating the frozen brine that I was feeding and then I left for not even a half hour. When I came back there was no trace of the cleaner wrasse anywhere. I checked the levels and ammonia, nitrates and nitrites were at 0 and none of the cleanup crew was eating him. Are they notorious for hiding in live rock or something because I haven't seen him anywhere. The clownfish is doing great though.
