My daughter was on vacation near old orchard beach. When tide went out they gathered crabs big and very small , Star fish can they survive in a reef tank. I told her cold water there but they have them in pail and all seems well as of today . I'm interested in the star fish some only size of quarter this is what I'm interested in . Can we aclimate them ? Well won't have pics of what she has till 7:00 pm or so . Her tank crashed cat unpluged everything I told her to put stuff in her new water and see what happends I don't want to kill my tank with some disiese or something. So are we nuts to try this ?
