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

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.

Nice scope shots. They look like ostracods. But they are almost certainly not your coral's issue.
Lots of tanks have them running around in the sand/rocks, but they don't eat coral tissue.
More likely they clean up what's dying.

At first I didn't think they were alive but after seeing more of them and then seeing a tentacle pop out of a couple I had to ask.

What is this little critter? Thought it was coralline at first then it moved!

It's a flatworm. That particular species eats copepods.

Thanks. Should I dispense with him the next time I see it?

[Sugar Magnolia]

No, those kind are benign.

Yes, it's a tritoniid nudibranch, eats corals.

So I got some critters to keep the sand cleanish while I get everything set up, and got a couple of hitch-hikers. Anyone any idea if these (there are 2 of them) are ok to have ?



Cheers

and if any one knows what kind of feather duster that is i would like to know also

[chytownprincess]

I have brown bushy hairy looking stuff growing under my I've rock. At first I thought it was cyano or dinoflagellates but now I am concerned about hydroids..Are they photosynthetic? Can the grow in shaded areas?. I will get a pic and post it as soon as my phone charges enough.

I have been reading through this thread and I am a little bit freaked out. I have a patch brown brushy things that are on the underside of a piece of rock. I originally thought they were dinoflagellates or cyano (been fighting both), but now I am not sure. Please help identify.

please.....

It's really hard to call from those photos. It looks like a ball anemone to me. But that's just an educated guess. They are mostly harmless (no anemone is completely harmless).

[dtb125]

thank you Ron i have a direction in which to research now.will try to get clearer photo tentacles seem clear with little tiny colored spheres on the ends. the tentacles also seem to be 2 and 1/2 times longer than the boot. if it is an anemone.
