In my experience, I've never had issues with organisms similar to this size that are aquatic swimmers. Unless, it was this: http://www.realmonstrosities.com/2010/07/giant-isopod.html Do you have problems with the aquarium?

Good biological indicator.

There's just no way to count them. They're too tiny.

They are beautiful. I was thinking about their life-span ( <1yr ) in sporadic or evolving eco-systems. It would be interesting to see growth and population of different types of nudibranch, as the environment or organisms to feed on changed.

I doubt you will find an aquariast that hasn't had an unknown thing in their aquarium.

When in doubt, take it out.

Looks like a nudibranch.

I agree. That is a nice clam.

You should do a mug, then pull it out to glaze.

You should get more shapes:
