New tank and anenomies

[meadbhb]

Hiya,
Before you jump to conclusions, no, I haven't bought anything to put in my tank....I'm still waiting for it to cycle.
However, last night, as I was studying the tank for new life, which there is plenty! I realized, I hadn't looked under the rock for life. Well, I found what looks like an anenomie!
So, since this little guy was on the botton of the rock, I rearranged my LR so it was on the top and in the brightest part of my tank. Upon looking at the rock again, I noticed yet another one a little further down the rock. I'm pretty sure these aren't glass anenomies. They're bleached out, the centers are about the size of a eraser head with long white tenticals with little bulges at the end of their tips.
I've got a compact lighting system with a 65w and 100w bulbs. I know this isn't strong enough for anenome's but I want to give them the best chance of survival as possible. The tanks been up and running since Monday. I've seen lots of fans, the two anenome's, a snail and lots of critters running around on the rock. Do I need to try and feed them or will the critters running around on the rock be enough to feed it? I've thought of taking some of the tank water out, thawing some brine shrimp in it and using an eye dropper to try and get some food to them.
Any suggestions, or should I start playing taps for them?

Your description leads me to believe they are Carribean Mushrooms. They do best in the dark or under rocks.

Hiya,
Bang...does this mean I need to turn them upside down again?
Wish the camera was working, pictures would probably help. I've seen mushrooms in my LFS and they don't look like them, is there a picture I can see? These guess don't have any trunk, they do lie flat against the rock, and look like they have a star pattern inside the circle of tenticles, which are long and flexable.

If my web site was up I could show you a picture. Does it have a pinkish center and whitish tentacles that end in a white ball?
If it's a Carribean Mushroom you don't have to turn it over but no bright lighting. If you feed it it will reproduce. I think they're attractive.

Hiya,
Bang, it looks like it has a green center, with opac tenticals with little balls on the end. It was withdrawn today so I decided to flip it over so it doesn't get as much light. It's probably trying to recover from being put in a newly set up tank.
I did a search for those 'rooms and it very well might be one. I've seen a lot of critters running on the LR, should I still try to feed it?
