Help IDing some stuff... is this Majano?

Is this Majano? I posted in my tank journal thread but I don't know if anyone actually looks at it, so I thought I should get someone else's opinion. There are a pair of them, around nickel sized and colorless. Both retreat into holes in the rock when disturbed.


And these I found not far away from those little anemones, they seem to be some kind of stony coral (they definitely have a skeleton). They also seem to be getting less brown and more orange since they are in a brighter position now, so time will tell. I thought they might be a pest anemone at first, but I don't think so now.

First one looks like aiptasia to me and the second one looks like a hungry sun coral..

Try feeding mysis shrimp when the polyps are extended.

Thanks for the reply... I'm beginning to suspect the anemones to be Aiptasia as well, though I generally see them brown to tan in pictures and I understand they are nocturnal? These guys close up when the lights go out.

The stony coral in the second pic does look somewhat like a sun coral, but the largest polyp is only ~4 mm across. Maybe I'll try target feeding them and see if I can get them to grow, thanks for the idea I think these guys close at night also, I'll check tonight after lights out.

Of course, they are pretty close to the tentatively labelled Aiptasia, so maybe I won't start feeding until I've decided what the anemones are and dealt with them (or not).
