Guess that Thing!
 

Hi Guys, I picked up some Live rock and got two hitch hikers i'm concerned about. Was hoping someone could help me out as to what they are and if they're ok to keep!

The first two are of a starfish that moves really quickly, his legs are about a 3-4 inches long! I am aware that i got a few brittle stars with the rock but one of this size???

And this is some sort of tube worm.. disgusting little thing to be honest, looks like an alien when it comes out. shoots out this sticky web that gets all over the place.. Not very keen on this little critter.. what can i do with him???

hey the first set of pictures are brittle star fish. They are reef safe for the most part.

the second one is actually a pest. I cant remember the name of it but the web like slime that it spews out is actually how it catches its food but the slime is toxic to most corals and will sting them. i would get rid of it as soon as possible.

Thanks!
 

Being new the Saltwater world... How would one dispose of this pest... "properly?"

well if it isnt attached to any rock, pull the whole tube out of your tank and chuck it. If it is attached to the rock, pull the rock out of thhe tank and chissel the thing off and chuck it.

how big is that brittle star? it looks huge

For the mucus casting worm (the name escapes me now) plug the end of the tube with some gel superglue applied underwater over the hole.

i've got one of those tube worm type things in my tank but it isn't anywhere close to that big! dang!!

Generally only the smaller variety are considered a pest as they are more likely to proliferate all over the tank creating sharp little tubes on all of the hard surfaces that will cut your hand if you're not careful. Read the article and make your own informed decision. I have had both small and large types and I personally haven't had any problems with them.

I have a couple of those tube worms and their mucus regularly is entangled on my sps, zoas and palys and clams with 0 ill effects...

I've had them for over a year like this.
