Hello...I'm finally starting to relax a little after having my new fish for more then a couple days. They are a six lined wrasse and false percula clown. Both seem to be eating well and playing around in the tank. Shortly before I added the fish I added a clean up crew from an online shop which consisted of 10 Scarlet Hermit Crabs and 10 Blue Legged Hermit Crabs, 3 Emerald Crabs and a couple brittle stars as well as a few different snails. Unfourtantly I've lost 3 red leg hermit crabs over the past few days. One arrived DOA, the other died after about a day later and one I noticed last night was out of its shell. All the other critters seem to be doing fine. What's sorta distrubing to me was the emerald crabs love the dead hermit crabs. In fact last night my wrasse and one emerald crab were sorta going at it over the carcass. Is this usual?? I was sorta worried my wrasse would be injured by the crab. Should I be worried or is this sorta nature at work? Both the fish and the inverts are being fed once a day, Formula 1 and Formula 2 pellets. Any thoughts?
