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

After doing some research is it possible it's a bud. Was just surprised it moves. Also can't find any images of what a bud looks like.

I would post this to the fish disease forum. This thread is more so for hitchhikers, you'll probably get more answers there.

Ok thanks

Huge chiton that lives under the sand surface and munches cyano off the tank glass. Crazy find. Must've been in my tank a year plus. Only seen him once before.

Hello

They are spirorbid worms. Harmless filter feeders. Good picture.

thanks

Pic of rock. White filaments in lower middle and upper left coming from rock. Any idea?

Are they hard or soft? If it's the latter then a sponge of some sort would be my guess.

Back to this, definitely a critter. It moves extremely slowly around the coral on the algae parts. LFS says maybe an abalone??

Had to catch a crab and broke down my reef and found this. Are they just some kind of mussel or abelone?

Hiya, so this 10/15cm nudibranch I think. Any advise, possible sump duty? Or just get rid of it?:hmm2:

Hard to tell from picture, but looks like a porcelain crab. Which is... which was... not bad. Their on the most part filter feeders from water column, very fun to watch their little feeding fans wave about.

I would just get rid of it, but it's up to you. I don't know how your sump is laid out, but you don't want that thing to crawl into your return pump or your skimmer pump.

Thanks bud, was hoping to ID it but I think your right it's scary big lol

Maybe these links will help with an ID. In most cases though these things always seem to be trouble.

Hi all, first post from me, lurked for a while and haven't need to ask a question since setting up my tank 6 months ago - a lot of info on here, thanks!

From the microscope footage and images below could you please help me identify the hitch hiker that is destroying my beloved Jewel Favia coral that has otherwise spent the last 3 months growing happily?

These things are numberous, all over my LR, white and approx 0.5mm in diameter and so very hard to photograph but microscrope footage included below;

N.B.

I'm not sure this is the correct place to post, please let me know if this should be a new thread in New to the hobby or the Disease thread and I'll take it from there.
