A few things unidentified... (56k run away)

[MikeP]

My guesses.

1. Neomeris annulata calcerous green algae that waxes and wanes - I have it, it dissapears then pops up again a year later for 2 weeks.

2. Pectinia sp.

3. Possibly Hydnophora sp. - encrusting variant?

4. Either Phyllangia or Cladocora sp. - a.k.a. hidden cup corals.

might be relative Gracilaria Salicornia I have kept a green form of this algae was easy to control

guess I should have said a little more about gracilaria it is growing out of controll in Hawaii ,in the wild ,but easy to controll
in the aquarium.

Yeah, the algae started as a few sprouts like 7 months ago when the tank was started, now it hasn't completely doubled in amount, but it has
definately packed on a few inches. The 2nd picture has always had that algae on it, and tangs and blennys never touched it in the tank it was
previously housed in, but also, it's not growing fast or even spreading, just living at it's current size for months and months. 3rd pic still throws
me off because we've recieved "miscellanious" pieces or frags from people once in a blue moon of that species, but it's never been 100% named
as far as I can remember (at least by the sources we've got it from). All other specimens we've recieved at the store are about 5"+ colonies, and
rather than encrusting on rock, or branching, it grows in similar form to Capricornis, in that it just keeps growing out as a flat plate, no long
sweepers, but I noticed it looks as if it has a few little sweepers during the day only, about 2cm at max. Only reason I wouldn't think its a Hydno
morph is because the other Hydno pieces in the same tank have turned brownish, and this one never inflates the way my Hydno's have, it only
has a carpet like complete covering of TINY polyps/tentacles. The last one did indeed come from my first batch of liverock, which was Fiji and
Florida rock. The only tricky part about it, though, is that it's structure isn't like that of Tubinaria, Scroll, Pagoda, Cup, or Sun Polyps, beacuse it's
nothing but a stony mouth (like a little Cynarina) surrounded with teeth, with med/large clear polyp tentacles that extend anywhere from 1-6cm
during the day, and up to 2x that at night (no sweepers with rounded nematocyst tips, though). It also never closes completely, its open at all
times, and instead of being a concave structure from which polyps extend from the inside, its a convex skeleton, so a good bit different than the
Sun Polyps in build. They are also very aggressive when it comes to feeding, as soon as they grace any type of food, it is strongly adhered to
and I'd say each mouth downs a whole piece of frozen krill in no longer than 15-30 minutes from start to finish. Maybe these details will help in
finalizing any IDing thanks for the help so far.
