What is this nasty this??

[jason604]

I just bought a wild caught acro colony today from JL and while transitioning it to my tank I gripped what I thought was its skeleton and it squirted water right to my face. Like what!! Acro squirting water? So I took a closer look and it appears to be something that resembles a dried date. Each time I pressed on it it would squirt water out pretty dam far. Anybody have any idea what the hell this is and if I should cut it off my acro? Its now in my tank. Bottom right of the pics

I could probably tell you if I had it and a dissecting scope. short of that... no telling what it is.

if you're worried, just scrape it off and toss it. there's a good probability that it is harmless though, just like the variety of surprises that comes in with live rock.

Probably some kind of tunicate, or sea squirt? Crazy!!!

They are just a filter feeder and good for the system.

It opened up now in my tank. I believe it is a sea squirt. Should I destroy or keep it lol.

yeah, the two siphons is the classic morphology of a sea squirt. One is the in-siphon and the other is the out-siphon.

It's a harmless filter feeder.
