Me and my wife are not sure what these are. the white one looks to be spongy with ventracles growing out of it. the green one is only 1/4" tall.

The first one is a sponge. They're pretty cool and will spread to dark areas of the LR. The second one is a type of algae. I've had it before, but was never able to keep it alive. A small cluster of them would be cool because they almost glow.

sponge and an algae.... I was trying to find the name as people have had it before and someone found a name for it. I have it in my tank and just keep plucking it. It grows back but it is slow to grow and spread so it is not exactly an invasive pest.

Thanks, we were pretty sure the white one was a sponge so its nice to have a second opinion (or 2 lol). as 4 the algae, I just wanted to make sure that it wasnt some thing to bad. Thanks again.

You can find some reading on that algae here, it's Neomeris annulata.

First one is definitely some sort of sponge.
