Cheers, I thought so. The white tail and red 'feathers' threw me, however, as the rest of the feather dusters in there are more of a beige/grey colour.

Saw this pink worm creature on the sand thus afternoon. Tank is cycling at the moment.

It's kind of hard to tell from the pictures, but it's probably just a harmless bristle worm.

Saw this on my glass this morning. No new corals or fish added to take for over 3 months. What is this 20170417_192550.jpg 20170417_192613.jpg

Really hard to say from the pics. Google spaghetti worm and see if anything there looks like what you have. If it is, it will probably find a good spot in the sand or on a rock and build a parchment tube to live in. BTW, if that's what it is, they are good filter feeders and do no harm in the tank. I wish I still had some, but my wrasse ate them all.

Yep, terebellid worm, beneficial critter.

I'm just starting my first salt tank (40b with 30 lbs dry rock, and 10 lbs live rock from the LFS), and I think I have my first pest. Is this a majano?

The "tube" rock piece was with some rubble rock and I liked the look of it. Anyone know what sort of colony it came from?

Any idea what this is? The 4 spots at 12, 3, 6 and 9 on the one in the top left circle glow orange under blue light.

Looks like some zoanthids.

My first thought is that they are palys, either that or zoas.

Cool! Into the tank he goes.

Is this hydroids are good or bad?

Nothing to worry about, they'll disappear on their own.

In or out? Apparently a bristle worm.

These are actually a great part of your CUC.

MuscleFish · 04/24/2017, 03:40 PM

Any idea what's that?

Do you know exactly they will disappear? There is more and more of them

Way too blurry to tell. Look up munnid isopods to see if it's a match. If so, harmless.

Perfectly normal, give it a couple of weeks.

Population of many little critters in our tanks will bloom, over populate and then die back or even disappear.

deputydawg88 · 04/29/2017, 06:13 PM

Found this in the refugium, it's about half an inch across (not including the legs), any idea what kind of crab it is? Sorry about the grainy picture, if it helps it looks somewhat translucent in its extremities.

This is a great thread!

Saw this guy hiding in my rocks for a couple of days. He is getting brave enough to come out into the light now.
