What the heck is this?

if that's the case, why would anyone want this thing in the tank. It's out-a-here!

 

its a very good filter feeder

 

Thanks to everyone for their help!

 

i found this ,but this is not gold just one man opinion
"Most everyone has heard of the horror storys of a cucumber "nuking" their tanks, I have never had this happen and know of no one that has. Now Sea Apples are a different story, I would never have one in my tank since they are the most likely to nuke a tank and when they do, its right up there with small nuclear devices."

 

still, my tank is a 29 gallon nano cube HQI. I feel better knowing that "thing" is out of my tank. I new to the hobby (well returned to it after 20 years away) and I'm amazed of the hitchickers I have gotton from my Live Rock.

 

everythi8ng dies...so again, I can't justify keeping it in a tank. Anyway, that's just my opinion. Again...thanks for eveyones feedback.... I appreciate it.

 

you said you saw something lurking on the rocks?

are you sure there isn't another one hiding there somewhere?

 

So far, no other hitch hikers..
