I appreciate everyone's response on this thread. The opinions and experiences with this starfish seam to vary greatly. Not only on this thread but also on other threads I have researched. My Tank is a 144 gallon with a 30 gallon sump. I have about 150 pounds of live rock in the tank. Half of the live rock is pukani from an established tank. Algae growth is fairly good. As far as this being an impulse buy I'm not sure I would call it that. I went to the LFS for a Brittle star but they were out. The man at the LFS who I would assume to be knowledgeable suggested the Red Fromia. I had no reason to not trust him being that he has steered me away from purchases in the past that would not be a good fit in my tank. AS far killing things in my tank goes I think I have a pretty good survival record. I have only lost 2 snails and a lawnmower Blenny who seams to have disappeared. I currently have 2 clowns, 1 wrasse, 1 pink goby, 1 yellow tang, 2 emerald crabs, 2 hermits, 6 turbo snails, 1 coral banded shrimp, 1 duncan, 1 RBTA, 1 nuclear green polyp, 1 pulsing xenia. All are doing excellent. I check my water parameters every other day, and I try to research everything in my tank as much as possible. So I can provide it a quality life. The starfish is moving and shows no signs of stress. I am still on the fence and will continue to research this topic. Thanks again for all of the advise.
