help id-ing/caring for stuff on LR

Hi! im kind of new to marine aquaria and just picked up some cured Live rock from a LFS. I am seeing some intersting life on the Live rock and would like to know if it is good/bad for my 10 gallon marine predator tank.

first up is a small brown anemone (sp?) that I assume is aiptasia. It is actually kind of cute. They are in a very porouse rock that I really can't see them getting out of. The holes are probably about an inch deep, maybe less. Do I have to worry about these 3 little guys escaping and reproducing (I've read that they reproduce by leaving a footprint or something)

Next I fount some featherdusters. They are little white tubes with bristls coming out. Featherduster, right? How do I feed these guys?

Next up: two little bugs I spotted last night. The first one was like an underwater flee. It hopped from one crevice of a rock to another and was whitish/clearish, and the other was like a tiny shrimp not much bigger than the thing described above. I'm assuming the first thing is a pod, right?

sry my computer will only let me post a little at a time. Anyways, I'm assuming the shrimp like thing was a shrimp. Do I have to target feed the pod/shrimp? thanks for the help and will update as soon as I find more stuff!

new thing! I turned the rock over and there are these bright, hard ink branching things. there is also a white one. Wish I could get a pic, but I dont have a digital camera. but they are little clumps, attached at the base that kinda branch out. I faced them towards the light, a 50/50 15 watt reef sun incase they are some type of coral. any idea what i is?

These are likely to be forams. There are alot of different ones, you can read about them here

If the anemones are aiptasia you will want to get rid of them now, they spread rapidly.

No additional feeding is necessary for the bugs.

well I dipped the rock with the 3 aptaisia in very hot fresh water and skewered out as much as I could out of the holes. All the featherdusters are probably dead too. I hope the pod and shrimp moved to a different rock. At least I still have a whole mess of featherdusters on my other rocks. Also, it does look alot like the things mentioned in that article.

A bit excessive, killing everything on/in the rock wasnt necessary.

it wasn't a large rock. I didn't want to see any more of those. Do you know if nerite or margarita snails will eat coraline algae? cause my nerites are being a little too friendly with my rock....

heh. Overkill wasn't enough kill. One of the sobs survived!

Nope their mouthparts are designed for eating fleshy algae.

I usually just hit them kalk paste, works like a charm.

I don't have kalk paste and I don't want to treat with deadly chemicals in a tiny 10 gallon. If it comes back I've heard of putting boiling water in a turkey baster and squirting in their mouths. Would that work?
