The first looks like some type of sponge. I had some on my LR when I got it. It was clear at first and turned cloudy as it died. The second pic looks like an urchant of some type. Hopefully someone can add or correct on these.

the second one looks like apastia. bad stuff. you'll need to get rid of it if it is before it takes over your tank.

See if you can get a better pick of the second one. I wouldn't evict it just yet.

The second is definately an urchin. I ended up with 11 of them from my lr. They grow very fast. The second one could be a sponge.

Aips can move, just not that fast.

The second pic looks like a rock boring urchin.
