What to do with unwanted tank member?

[kristofer hathaway]

I am wondering what others do when they have a tank member that is not fitting in well. I had a emerald crab that randomly started eating my coral. Had "him" for months and never had a problem. He got a taste one day and wouldnt stop. I quarantined him in hopes to yive back to LFS but they dis not want him.

I'm surprised the store wouldn't take him back for free. You can try keeping him in the sump until someone wants him.
