First pic looks like a 'Spanish Dancer' nudibranch, second a mushroom if that's the thing you're on about?

Not really sure about the others as I can't see the pictures too well

Yes, it's a sponge eater. It likely won't live long, but shouldn't be a problem in your tank.

Nudibranch ? Thanks for your advise . I also heard some sounds at night I suspect there is also some mantis shrimps in there .

I observed my sea urchin and star fish sticking themself on the upper area of the tank , is there possible some natural predator out there that they may be scare of? I have some fish die off not sure if it was due to fighting each other or being eaten by some hitch hike ? I loss my old fox face and a sea urchin since I added new live rocks
