Bad guys?

[JMM744]

Caught a nudibranch hanging from the stem of my frogspawn. Pulled it off with tweezers. Left a piece behind though. Also have some stuff I am not sure about. Pics to follow. This stuff ok?
What about this guy? Dead center , oval shape, light color.
Thanks guys. Jim

In that first pic... I think you pulled off a frogspawn "baby".

Perhaps the oval gut is a stomatella snail?

The first looked just like a picture of a nudibranch with the frilly edges etc.. it was a pretty green color though. Hope I didn't kill a coral. It was longer and flat looking till I picked it off.

the shape is much like this. Colors were a bit different. I do have what shows in your picture on my hammer coral though. They grow under blue light.

How about this...
It's starting to grow across rock and some of the frags.

That's a sponge^

Ok, thank you for the confirmation. It's growing well in the tank.

Sorry to hijack your thread but @Lionfish Lair this was the stuff I was trying to id the other day. You had mentioned hydroids? Mine are just starting to form on some frags. Has the same branching pattern and round branches.

You can tell JMMs is a sponge because of the siphons. It could be something like a Clathrina coriacea.

You should be proud of the sponge means your tank is thriving and tank is stable
