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

Thanks

In or out? Apparently a bristle worm.

In...

These are actually a great part of your CUC.

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.

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.

About to have a meal?

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

Just bumping this onto the new page.

Why don't you pull it out and take a better photo and post it. From the angle you took the one you posted, it's almost impossible to tell anything.

It looks like a ruby red mithrax, commonly called an emerald crab. They come in both the common green and the less common red colors. But a better pic would help. It eats algae and most (not all) consider it a good member of the clean up crew. I always have them in my tanks.

Apologies, hopefully these pictures are a bit more enlightening:

Having just looked through the glass from the bottom up, the tips of its claws are a darker grey colour as well.

Looks like some type of swimming crab. They are getting generally very destructive.
