What is this?

[Fanof49ASU]

This is almost transparent, that I found floating in the current. I can't see the base of it.
Any ideas?

Just some zoa/paly pics I thought that I'd share. This is what I was doing when I found the ufo.

Here's another zoa that I've raised from a single polyp. They're hard as heck to photograph, but the yellow and oranges blend beautifully.....and they're much more vibrant to the naked eye.

If it was free floating/swimming, possibly a jellyfish... do you have hydroids that you know of? hydroids are the beginning stages of jellyfish.

Yes, I do have hydroids.
Are you serious? The beginnings of a jellyfish?

[Lint_Licker]

Yup, I found out the hardway, got stung while cleaning out equipment.

Thanks Lint.

I wonder just how big they'll get in captivity? I guess they could damage my zoas......next time I see it, I guess that I should pull it out.

[Lint_Licker]

they can damage you. Im more concerned about getting stung by them, some are deadly. I would keep an on the kids too, make sure they aint playin in the water cause they can hurt the kids more then you. Also some are kinda like a bee sting, if you are allerigic to bees, ya dont wanna be messin with them.

[Shocky]

these can be very dangerous please use extreme causion. Possible death can happen. If you have anything from Australia in your tank you might be at more risk. some very small jelly fish from the great barrier reef are deadly to people. Diver have been caught in jelly fish storms and did not survive. Please use caution.

[Lint_Licker]

Im sure you re referring to the box jellyfish which are common to australia, and have been found all over the world, even the carribean. It just takes one sting from a box jellyfish to kill you.

[NeveSSL]

Nope... not the box jellyfish, but the Irukandji. (http://goaustralia.about.com/cs/practicalinfo/a/irukandji.htm)

The Irukandji jellyfish (Carukia barnesi) is a small, extremely venomous invertebrate of the class Cubozoa (Box Jellyfish).

[Lint_Licker]

Hydroids(very vague and commonly misused description). There is over 2700 known species. The box jellyfish is the most deadliest and found through out the world, australia having the highest death toll, it starts its life as a hydroid just like all other jellyfish.

Another thing, this may or may not relate to this... Its become common practice to call all of them hydroids since they look similar at that stage but there is actually 3 different types that fall under the phylum cnidaria. Everyone has 2 stages in their life cycle, polyp and medusa. Medusa being the the actual jellyfish and polyp which is what we typically see in an aquarium (Ive removed a few hundred of the medusa's out of one of my tanks recently).

Hydrozoans-Man-O-War being a common type we should know. They can reach up to 90 feet if I remember correctly.

Scyphozoans-Cassiopeia being the most common seen in the aquarium trade.

Cubozoans- The Box jellyfish belongs to this family.

[Fanof49ASU]

Wow....I may never reach in my tank again. I usually use tweezers for all of my moving/rearranging.....now I will all of the time.
And yeah, I'm allergic to bee stings.

[Lint_Licker]

I broke down my tank that I had the jellys in. I went and got some shoulder length disposable gloves and removed everything. Let all my liverock sit out on the porch for while, then took a propane torch to it all, then took a pressure washer and cleaned it and started that tank over form scratch.

I found a very small Jellyfish in my QT last year after the Frag Swap. I was able to scoop it out and take video of it swimming. I'll look to see if I can find the mpeg.
