Looks like the some type of feather duster tube. Is that a opening on the top?

it's a Vermetid gastropod. it will send out a web-like net to catch food particles in the water column and pull them in.

yeah it has 2 openings, will their size increase?
sorry did i post in the wrong place? im new to forums

This was the perfect place to post it. The openings don't increase in diameter but there is another species that is thinner. I have both types.

they do tend to become abundant, not a bad thing really as they're good critters to have. Just watch your hands when working in the tank they can give you quite the poke!

I've got quite a few Vermetids in my tank. Big ones and small ones. I have read that they sometimes clog pumps when their population grows too large. I sometimes find deposits in my pumps, but nothing that affects performance. Once in a while I go on crushing spree with a pair of forceps to eliminate the ones who cast webs near my corals, but I otherwise leave them be.

They will increase the length of their tube until they clear any obtructions immediately near by.

Here are a couple of pics to illustrate. The first shows my open brain it is about 7.5 x 5 x 3inches tall in the pic.

The second shows a vermitid snail. The tube is about 2 inches tall. It is almost 3/16 in diameter.

Thanks, got lucky and beat everyone to at my now defunct LFS a year ago. Seems to be pretty hardy with standing a little lazy management.

sometimes the best way to care for a coral is not to if that makes sense ^

Yea, the more we try to make it perfect the more we destabilize things.

I have one that is a deep purple? is this a normal color variant? or does this mean mine is a different species? Thank you for any answers

Aaron, I have some that are covered in purple coralline, could that be the case with yours?
