I have an orange linckia that I ordered from this site. When I got him (Dee Brown is his name), he was fairly small, maybe 3" across. In the 6 weeks that he has been in my 90 gallon with approx 100 lbs of LR he has really fattened out! I have never seen him "eat" anything in particular but he is constantly moving over the LR and some days is climbing up and down the glass. Very active and fun to watch. I am wondering Ophiura, if the blue stars are similar in nature and requirements?
