what is this orange thingy??

[heteloto]

it started to develop on my live rock months and months ago and got pretty large.

 

[heteloto]

i am thinking sponge??

Looks like the creamy white sponges I have in my tank.....trade you! Your's has much more color!

Looks like it could also be a tunicate/sea squirt to me. Very cool, nice color, whatever it is.

+1 on sponge, I had a lot of them in my tank and after I added my coral beauty it ate all of them

 

[Reefmack]

Looks like an inlet and outlet hole (siphons)? I used to have a tunicate that was very similar to that, but yellow.

+1 definately not a sponge.

I'd agree on tunicate as a best guess per the photo.

 

[Uslanja]

We're weighing in on it being a "tunicate". Nice looking rock! Is it from Salt Water Paradise?

 

[heteloto]

HA! Not from Salt Water Paradise but he is who I go to for just about anything. Not exactly sure if he is totally knowledgeable about certain things but he at least has passion. I usually go there, look for something I like then drive all the way back home and research it. He is super cool.

Awesome, NEIGHBORS!
