Sea Slugs in tank.

[bane]

Have some white sea slugs with yellow fin-like-appendages on the back ...

Very small ... like 0.5 cm

Initially only a couple ...but they seem to be growing in numbers ...

Any idea what do they eat ?

Will they attack my polyps and mushies ?

Is it that you just bought zoos? If yes, then these are pest. Kill them by put zoos into plain fresh water 10mins to kill them. For those crawking adults, suck them or pick them up and then throw into fresh water. Will eat and destroy yor zoos colony.
