Id suggest that the next time you see the starfish take it out of the tank. It looks like a Arista StarFish. They stay really small (about 1/8 inch) but multiply like mad, once established you will have loads.
Also some of the species feed on corals, but they are usually have a darker body, All the ones i have in mine are White\Blue and feed on coralline algae but the pure numbers get unsightly.
(bit tipsy here, bed time tbh.)
Aye ive been told its ok for a bit. If i get a million of them or they start eating stuff i'll combat them
It keeps itself in my "inlet" filter bag (the only way water can pass through) and is probably munching on the caught up algae in there, no harm at the moment.
One of my hermits attacked another last night, kicked it out its shell. Then started nipping it. Separated them though, and the beaten on promptly lost 2 legs, however ive been advised it could be (and most probably is) a moult.
The "dominant" hermit also rushed over to the buttons when i put them in and just sat on them for a good hour, as if he was king of the hill. Hes currently climbing to the highest point of my rock atm, little blighter.

Then I'm thinking 2 regular clowns (orange) with one or both being a mis bar.
However i'd love a black and white one, just not sure as to put a bnw with a "normal" one, the bnw would have an orangey nose/fins, which isnt what I'd like, but i can't have a proper bnw as they are diff types. So i'm leaning towards a mis bar'ed orange pair. (blacks look so pretty though)
just seen this though:
I'll chat to the LFS owner i found the other day (in stoke, awesome little shop)
