Would like to know if these guys are safe and what they are. New to salt water
Might be wrong, but looks like it is aiptasia. This little jerk will take over your entire tank. I would qt the coral and or buy a product designed for killing it. (Be sure that it doesn’t kill good corals)
Upon research I am starting to lean that way. Had lost some damsels to them... joys of mother nature.
Sorry for your loss. Kill the aiptasia with liquid fire! (High power laser or store bought killer)
There are a ton of aiptasia killers out there, but one that worked particularly well for a member here was Berghia Nudibranches.
