JELLY FISH?

Please help me ID ,Ispot about3swimming things in my tank they look like jelly fish , but not sure and if they are not idea what kind either, they have the shape of a church bell, and you can see through them in the top or head they have a white dot and the body is clear the bottom seems like a womans skirt and it's also white like the head. swims like jelly fish . i haven't been able to take a good pic , they are very small and move to much.
My tank is 1 moth and change days old. Do i need to worry about them in case they grow bigger. will they harm any corals when i'll get some.
Thanks

 

allan take a pic and post it.

 

To small ,can't get the camera to focus, also they move a lot also today i spot about 15 of them one was on glass and it seem to have tentacles to

 

How about a drawing? Words can be so woefully inadequate! It does not have to be a great drawing! ;D

 

allan, if they look like the ones that were in my tank i would assume they are jellies.

 

i love jeelyfish and am addicted to reserching them...spent hours of time identifying diffrent species...so if you could get some what of a pic or drawing then it would be great!!!!!!! and i will help you with all of my jellyfishing skills!

 

Sorry , haven't been able to get a good pic , and my drawing skills are worst than a preschool kid ;D .
thanks for karma BIRDLADY.

 

Are they somewhat thimble shaped...dome top with an open bottom....tanish yellow in coloration and about 1/16-1/8" (the size of balls in the bottom of a glass thermometer)? IF so....i dont know what kind they are but the are jellies...they randomly appear at work.

 

Hey sea splendor, you are right on the money, that's what they look like and they are about that size to. sometimes i see them and sometimes i don't, sometimes they attach to the glass and they also have small tentacles in the bottom.

 

Ya i like the....they seem to come in from LR shipments from tonga and jakarta....They live on the glass or rock at first and once they reach a certain size they detach and bob around the tank....very cool but i have no clue on thier care or anything. I kept afew alive in a large beaker for a few weeks.
