In response to a small algae growth I was having I purchased 2 large turbo snails from my LFS
. After acclimating them to my tank I put them in and walked away. I returned to check on things after a few minutes and this big bruiser of a hermit that I have was sitting on top of one of the snails he had flipped upside down furiously digging at it. I took him off and set him on the other side of the tank and watched the snail for a few. It did not come out of its shell. I left and returned to find the naughty crab at the other snail shell doing the same thing. I took this snail and put it up in a piece of decorative coral I have to get it away from the crab. The next morning I awoke to find the hermit with both snails, one on each side of him, snails pulled out of the shells, moving from shell to shell. I swear the little punk was looking at me like "thanks for the new home" summer home..... winter home..... he never ate the snails, just wanted the shells.
While the story is somewhat funny, I am concerned that the crab may have to go. The loss of the snails is not good, and I am worried about him attacking my other fish and inverts. I think from what I can tell he is a standard hermit crab. He does a great job of keeping the tank clean so I would rather not get rid of him
Any suggestions would be appreciated.
I also have a questions about Tangs in a reef tank but will post that later.
