BLACK NUDIS ?

[Myka]

typical Zoa Eating Nudis are grey-brown as you pictured reefwars, not black. Having said that though, since he found them on the Zoas they are likely some sort of Zoa Eating Nudi, but who knows?

Wingedfish, good call on the black Stomatellas, but they shouldn't be that difficult to remove, and a coral dip would kill them or at least make them fall off.
