Hard to say from the quality of those pics, but I think they are sponges and shouldn't be a problem. We'll see what others think.

I would agree, probably sponges unless it moves?
If they move then they are sphaeromatid isopods, harmless.

They definitely move. There's 100's that come out after the lights go out. My searches led me to the sphaeromatid as well. I just couldn't find any white with brown spots. They're primarily on my zoas. Just wanted to make sure. Thanks!

Three weeks ago when i went to the LFS to pick up live rocks, i had a clerk sort through them in one of the big tubs they were in, when suddenly a small moray eel came out from one -needless to say he got very startled 
Hows that for a hitchhiker!

Apparently the pictures didn't actually attach, so here's the imgur album of the crab.

Took it to my LFS only for them to find one that was destroying another colony, so I'm guessing it was some kind of gorilla crab.

What the heck is this?
Orange blob swimming in my aquarium, changes shape, about 3mm? long.
Moves by pushing water around its body like with cilia as opposed to wiggling - see video below.
On drying dish.
You can see water movement near its body by the moving particles

Edit: I have sun coral- but no signs of it releasing larva - ever.
I also have sponges which apparently have a free swimming larva, but none near that color.

Can you help me identify these?

These guys were small for a long time but seem to have taken off as of recently. After battling aiptasia I am now learning the valuable lesson of identification. Can you help me identify these pink guys?

They look like Palys to me. I've had some that grow slowly, but most seem to grow pretty quickly. I'll allow them in my display refugium and in my 65g shallow reef local tanks, but not in the 125g main display tank. I consider them too invasive to try and keep under control in an sps dominate tank.

Very cool! Tunicates are very hard to keep in tank. I just picked up a decorator crab that has a white & orange hard tunicate on it's back. I wonder how long it will survive and what the crab will use if the tunicate dies and goes away?

Mine are growing really fast considering everything I've always read and experienced showing how low their survivability is in the aquarium.Very cool! Tunicates are very hard to keep in tank.
