Hi there,

I moved a piece of live rock today and found this...



Is it bad? What should I do with it?

I also have this furry purple stuff growing on a piece of live rock. Any ideas?





I also have noticed a baby blue worm that looks like a thin ribbon made out of snot. It comes out of a hole in the live rock at night and floats around. I don't have a picture but is it harmful to coral or fish? Should I just put some epoxy over the hole?

Any advice would be awesome. Thanks in advance.

Brissle worm. Clean up crew. But lots or big ones is a sign of over feeding. Garranteed you have lots more

The snot worm is probably a spegetti worm. Harmless

Red fuzzy stuff could be cyano I guess

+1 Bristle worm they are in all systems overfeeding or not. A bonus of live rock

Purple fuzzy thing is hard to tell could be a sponge. Pretty though.

The purple fuzzy thing almost looks like a flower or something you can see individual hairs if that makes sense. I used my DSLR but I'm not much of a photographer. I will see if my wife can get something better. Any tips for taking pictures?
