Jellyfish art

HI I am new to this forum I have been meaning to join for awhile but anyways now I have.
I have received a new tank for Christmas a preset up nano jellyfish art tank and the directions tell me to order the jellyfish the day after I set up the tank, but that makes me nervous because tha tank has not even had a chance to cycle and it only uses biological filtration with an air pump to a irate the tank. So my worry is that the tank won't be able to cycle befor I order and acclimate the jellyfish and not have the biological filtration in requires. They said they send the jellyfish overnight with a small piece of live rock,but I don't really want to take the chance I just today went to the local fish store and got some live rock and mixed it in with the substrate it came with. I will link a photo.
So my question is if anyone has any experience with jellyfish and how long should I let the bacteria colonies build up in the substrate it came with?
Thank,
cole
it won't let me attach a photo on here from my iPad I will try to figure that out...

 

welcome and I hope to see it soon

 

 

looks great!

 

Thank you do you have any experience with jelly fish?

 

well ive tryed to help the ones on the beach. but other then that ive only been wishing.

 

Be careful with the ones on the beach they will sting you even after they are dead lol my sister got stung like that lol she thought it was a plastic bag on the beach and picked it up

 

oh the ones down here are the white kind that get the red stingers. as long as they don't have red dots on them they are fine to pick up.

 

I see...

 

I've always wanted one of these! They are so neat! Careful with anything sharp in the aquarium, it could hurt the jelly fish. I have some links you can look at, but I can't help with any care. Good luck and it looks great!
