Pix & ID: Critters that come in your rocks: the good and the bad.

hi rc members so i just set up my first tank and i noticed some nice looking hitchhikers but still don't know if they are good or bad and since i want to have a reef i need your help identifying these critters i have read the whole thread and still couldn't get figure out what i have on the live rock so here you go

the anemone looking things look like aiptasia which is a bad hitchhiker.
 
SPotter, I have no clue what those are, never seen anything like it before. I'd have to look around, just not sure where to start LOL.

Lightning whale, the 1st pic looks like a bleached zoa. Not sure what I'm looking for in the 2nd pic. 3rd pic also looks like some kind of bleached polyp, but it has a lot of tentacles, which makes me think not zoa or paly. What do the 2 polyps do when disturbed? I'd like to see at least the 3rd pic one closed up and face on if you can. Neither of them is aiptasia, but I'm a little worried about that last one not being a polyp.
 
thanks Sushigirl. I will keep looking around. they scrape off the glass like anemones but I just dont know. I will try to get better pictures.
 
hi thanks for the replay sushi girl the first one contracts and close up when touched and you can see it moves it withdraw all its tentacles inside when touched

the second one i am referring to the big brown area on the LR which i can see small hair like on it when the lights are on and i can clearly see bleached out parts of it (i am guessing brain coral but that's just me being optimistic) and there are some small orange mushrooms on it :)

the third one changed places many times today it was moving and it finally settled here is a close up shot of it



and i found a new hitchhiker which i think its something interesting it looks like a mushroom inside a tunnel but with a green mouth in the middle i tried and touched it and it closed and shrunk to its tunnel



sorry for bothering you guys but am still learning and i need as much info as possible
 
Lightning whale, where did you buy the rock?
The original 2nd pic looks like where a brain or other coral used to be. There's not any flesh on it, is there? As for the orange things, google orange ball anemone & see if that's what those are, I thought I saw ball tips on one when zoomed in. First pic here is not quite what I was afraid of (majano) I don't think, but definitely is some kind of anemone judging by this pic & it moving around. Rock anemone, maybe? Not sure.
Can't tell on the last pic, I'm on my phone.

I have no idea what's in the last pic, their color is so dark I can only make out a mouth. They're each in an individual tunnel?

I get these little buggers on the glass a good bit, but normally only after the lights go out. The tank only contains my CUC at this time.

Sorry for the iPhone quality pictures.





 
I noticed these growing on my back panel glass in my frag tank and then on the bottom of this piece of rock. They look like flowers or some kind of clove polyp and close touched. Not the greatest pictures and the color looks to be green and white.

Thanks for looking and your feed back!

Could be a type of tunicate...maybe.

The first pic looks like a little rock flower anemone. Second picture, I can't really tell either, it's too dark.
 
thanks sushi girl for helping us out i bought the rock from the LFS and i live in the middle east
i think i have figured what they are the first two are rock anemone the second pic has brain coral with good amount of flesh alive but due to my lack of experience i think it will die and the black things on the rock i think are black tube coral

I think those black things in the picture might just be some type of palythoa.

Sugar, I was wondering if those were tunicates, but spent the day yesterday hunting down snail names LOL.

Lightning, I was curious about where you got the rock because due to CITES here in the states we can't buy imported rock with any corals on it, which also led to the question about flesh on the coral skeleton.

Steve718, I saw a TON of snails like your white one, did you put a message out on the inverts board about it?
 
I had that happen with amphipods in my fuge when I went on vacation last year for a week. Had an expert friend take care of my tank too. No idea what happened to them. Added some new chaeto & built them back up. Had almost all of them disappear this summer too when our chaeto disappeared & we were home all year. Added more chaeto again. I wonder if we'll lose them every summer?
 
What is making these sand tubes?

What is making these sand tubes?

I tried searching but could not make an ID. These are small tubes that get easily churned up when a snail might plow through them. I can occasionally see many small thread-like tentacles stretching out and pulling back sand grains to the tube but I do not see anything more than that. The tubes in this photo were all made overnight, the length of each tube is only about 1.25 inches.
Thanks for helping a total newbie!

Sorry, I am wrong, Cloak is right. is call a chaetopterid worm or Spionid worms. I still have hundreds of those, just wrong on the name. They do no harm, if you ad more cuc and/or feed less food the population will be reduce other wise they will populate much of the tank.
