Mac, thanks for the explanation. This zoas are new in my tank I had a little colony, like 15 polyps, that came with my live rock and they just disappear, thats why Im taking a closer look to the new zoas and tonight I found that red thing over them.
I was thinking it was the "shrimps" were the problem because every night I see them hidding in the base of the zoas, but maybe Its something else. About the cyano
I dont know where it came from, all my levels seem to be fine:
1.024 / 32
I also have like 3 polyps in the sump, and they are ok, so I think something is killing what i have in my tank.
I only have 3 reef safe fishes, 2 feather dusters and a sebae anemone.
What came with my LR
(what I have found up to date)
1 stomatella, 2 brittle stars, 1 limpet, a lot of amphipod, somekind of strings coming out of some holes in my LR
(someone told me they are spaguetti worms), a little crab and something that looks like a flat worm.
I have not a right ID for the crab and the flatworm, but here are some pictures
