Something growing on LR
 

I have single large piece of tonga branch LR.
It has a few patches of some white growing on it, and when the moonlights are one, the light up with little green dots all over them. Very noticable.

My camera is super lame, so i cant get a quality pictures of it.

We need a pic. Could be a sponge/tunicate, or possibly even a Ricordea or something...

Here are some links to help identify some of your hitchhikers :mrgreen:

My guess would be sponge - I've got quite a bit growing in my tank. Sounds similar.
