    It is good, don't worry about it, part of the LR, some sort of sponge/squirt, normally good for filtration. Seen loads on my rock.

    It is a sponge, the reason it grows on the underside of the rock is because it doesn't like the light, so you will harm it if you put it in view, leave alone and it will filter your water for food.

    Yes, they don't like excessive light, but I've got a few sponges in full view (and some of them grew there out of their own accord) - you could put them at the ends where you don't have that much light, or under an overhang. Some of them make really interesting "patterns".

    The exact name for this "thing" is a "branching ball sponge" (Leucosolenia sp)...

    Warr, not to be argumentative... but I doubt that light necessarily hurts these things (I've had some grow under direct light). They do change color depending on lighting though (and that can be kinda fun to see). I've had some of mine go from white to orange when put under stronger lighting.
