Any idea what this could be, looks like a sponge?

Found this off of a nature video on YouTube, curious to hear if anyone knows what it could be. I'm talking specifically about the green sponge like structures. Might be really cool to have in a reef tank!

Looks fascinating! Could be some sort of sponge or tunicate, but I'm not an expert at IDing critters. 🤔

Haha thats hilarious, you mentioned tunicate so I googled and look what was the first image that came up:

 

Atriolum robustum

 

exact quote from image: 

 

Quote

The Komodo National Park site in Indonesia was inscribed on the World Heritage List in 1991. The site hosts "Komodo dragons" (Varanus komodoensis), a unique species that exists nowhere else in the world and is of great interest to scientists studying evolution. The rugged hillsides of dry savannah and pockets of thorny green vegetation contrast starkly with the brilliant white sandy beaches and blue coral-rich waters offshore. Pictured here is some of the diversity of marine life in the park: three species of tunicates ("sea squirts") - Polycarpa aurata is purple and orange, Atriolum robustum is green, and the blue is from the genus Rhopalaea. (Nick Hobgood)

Further research also shows that it could be another similar looking tunicate by the name of Didemnum molle.

And finally the difference between the two from wikipedia: https://en.wikipedia.org/wiki/Atriolum_robustum

Quote

This sea squirt is sometimes confused with Didemnum molle but that species has a network of internal channels and exudes mucus, making it sticky to the touch.

It looks almost identical. The color is a bit more dull, but that could just be from the lighting difference between images. Who would have thought lighting could make such a difference! I'll definitely do more research on it but nice job!
