Jellyfish?!?

Woke up this morning turned on my lights, and this yellow jellyfish looking thing shot up to the top of the water.

Have never seen it before,anyone know what this is and should i put it back in my tank?It looks like a featherdsuster head that pulses like a jellyfish and has a seed on the bottom of it it is all yellow.
But the featherduster head is covered by a clear bell.

Should i put it back in the tank?

 

Nope, I wouldn't put anything in the tank you don't know what it is.

Can you get a better picture or video of it in a bowl or something. Curious as to what the bugger is.

 

Ok here is another video of a better idea and a really good picture!

It is awesome looking, I can tell you that much. It is still just swimming around!

Looks like a jelly fish to me.

Odd you're the second member recently to have jelly fish in their tank.

I am sure it will die off soon on it's own.

Myself I would probably put it back in the tank, I do not see any harm it could cause.

 

Neat find! 8)

 

Very cool find!
