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

I have no idea I could not see it from the angle I was at. I think it is the same species as this guy that jumped off my LR when I first got it.

I don't believe they are the same species. I believe white crab to be in the Xanthid species, and the red crab species to be Mithrax. The white crab, if claws are dark at ends, i am thinking the Leptodius family. Shot in the dark , maybe Leptodius sanguineus. The red crab looks like a red emerald crab to me.

With pictures of the white crab fuzzy and from behind, hard to tell for sure.
 
ID for this anenome? How bad is it?

ID for this anenome? How bad is it?

Found it hiding deep down in a crack among my starburst corals. Seems to dislike the light and expands in total dark and shrinks in the light. Tough to get a clear photo due to the extreme angle. This photo is looking almost straight down. It looks to have short tentacles, a bright white ring at the base of the tentacles, and a reddish mouth area. It's moved out of that location and is now on the underside of the rock. It's size is similar to a zoa polyp but the stalk is thicker.

If it moved then most likely it is some sort of anemone. I would be comfortable guessing that it is a majano
 
Sea maggot??

Sea maggot??

What is this little guy? It looks like a maggot with a longer and slender body, about 2 cm long. It comes out at night, crawls on rocks and glass.

Mistakenly posted these pics in my introduction post instead of here. Can you all help me ID some of these critters that came in on my LR?

Please excuse the dirty glass!

A full tank shot. I've got a little filter running without media for flow, and I used it to polish the water when I first added in the live sand. As you can see I got some nice sponge, and really great algae (I think)

I'm not at all sure what this guy could be. Looks like a clump of debris, but he's got tons of little feelers that flail all over the rock.

Was afraid this was aptasia at first but I don't think so. Seems more like some sort of polyp (I think that's right) I fed it some brine shrimp tonight and it is way less shy now. There are quite of few of them, more popping up all the time out of holes, some look a little different.

As you can see here!

There a pretty large on under the arch there.

I also have some sort of snails, a tiny little crab, a hermit crab I can't seem to find now, and a host of other critters. I wasn't prepared to have this kind of life already and I really hope my main lighting gets here soon!
 
The first is a terebellid worm. Harmless filter feeder. The second is a mojano anemone. A pest that needs to be eradicated.
 
Oxford, I. Have no idea what that could be, sorry.

AUChief, with the pointy tips, I'd have to go with aiptasia, majano usually have rounded tips. Either way, Sugar's right that you need to get rid of them.
 
Aww man, that stinks. I've looked a a lot of pictures of aptasia and mojano and these don't really look like either, but a lot of the icutres look different from each other so I guess maybe they vary in appearance. Their tendrils look more lettuce-like than the picture I've seen. The way they are all over the rocks though makes it seem like them being a pest is very likely. Any chance it's some other pest I don't know about?
 
It's definitely some kind of pest anemone. There is a large variation in aiptasia species, not sure about manjano species. I have had a few very tiny anemone species in my 55 for almost 2 years now that are still tiny & not spreading. I haven't been able to ID them yet, but they don't act or look like aiptasia (not growin/spreading all over). The size, reactions to food & being disturbed, and how yours are all over just screams pest anemone to me.
 
OK.. I have not added any LR in over 2 months. I have added a ritteri anemone and some conchs and snails.

I did some aquscaping and moved around most of my rock 2 weeks ago.

I found this moving. I tried to pinpoint it but all I have found is it is unidentified until it gets bigger. I found none wit this color though.

Any ideas?

Not sure how many asterina species there are, but I find whatever you have intriguing because each arm seems to have a small split in it. Never seen that before. I'd be tempted to say asterina, as well, because they can be bluish in color, but the split arms have my interest peaked. The music cracked me up, BTW! Not sure I have time tonight to scour the internet, but I might have time next week if my memory doesn't fail me. Maybe they'll have an invert book for sale at MACNA next weekend that I can buy.
