Hey,
i would say that no seastars are for beginners, since they are very very sensitive and most need #1 a lot of
live rock for it to feed on or #2 a lot of
live sand for it to sift its food thru...
you have no inverts right?
but since yours is only a FOWLR.. i would suggest a chocolate chip star? one of the hardier seastars.... that you can hand feed...
but remember... you need to
acclimate it right.. takes like 3-4 hours.. you cant rush it... or youll run the risk of losing it to acclimation shock
