White thing may be aiptasia.

The star fish looks like a Red Sea Marble to me.

did you catch that star fish at the beach? i live on long island and it looks very similar to what we have here on our beaches.
the second looks like hydroid jellyfish.

 

[sebae09]

im not positive but i think all jellyfish are bad. you might want someone elses openion also.

 

[teen]

the hydroid jellyfish are common in new tanks and should clear up in a few weeks. they can sting fish, but nothing to be too concerned about.

 

[fishieness]

yeah. the hydroid jelly fish are nothing to be conserned about unless you have very delicate fish such as seahorses, esspecialy the dwarfs.
