Sand Star missing digits

[Aquaholic]

Well...

I have had my tank going for about 3 months now, 2 inch bed (small sand) I also have a goby and some snails to sift the bed (i didnt think it was getting sifted around enough so i bought the star. It seems healthy, the legs look like they more "fell off" i guess.

40-45 gal tank "tall cube"
60 lbs of live rock

P.s. hes a fairly small one (leg to leg only about 3")
