Wow, no I have never seen anything like that and I have been involved with saltwater stuff since 1997. Its cool though.

Hydroid jellyfish. They usually show up in new tanks, and quickly die off.

Thanks, Unsure if it's hydroid (picture) but maybe I'll see when my blue lights turn on. my aquarium is 4years old. I assume it was an hitchhiker from a mushroom I added beginning of April

Hydrozoan jellyfish and more and more of these show up this time of the year and have to be siphoned out with 1/4" tubing and discarded. At times they colonize in a dark area making it hard to reach them. They are harmless otherwise and not long lived- just a nuisance. Their tentacles are stick which is why water flow does not affect them much

This is a hydroid. You have hydrozoan jellyfish

is there a way to keep them around?

Its an upside down jellyfish. I have had them in my tank as well. They go through stages, right before they are free swimming they are attached to rocks usually.

This is what they look like before they go into their swimming stage.

Not that I know of as they are short lived.

any idea if you could keep them rolling in terms of reproduction

 

[vetteguy53081]

reproduction I would research but generally requires a constant food source

I think this is what it is.. medusa stage., I have only had one aiptasia (that I have seen) on a new frag 2 months ago ... which I removed (cut off/removed/ intact/ without touching it)

Do these medusa jelly fish harm corals or fish, also what do I look out for meaning how do I find early stages on my rocks, thanks

 

[Bucs20fan]

Fish, specifically butterflies will feast on them. They will probably never be gone, I have a CBB that eats them alot, and still have the polyps in places the CBB cannot get. I dont think its hydroids that you have. I think its upside down jellies.

So casipoia species?, it's new to me as I only seen this today, someone mentioned hydroid so I googled, It don't look similar
I tried taking pictures under blues with yellow and orange filters, nothing florescent but it is tiny



It's genuinely like a new spieces for me and weird to see so all help is appreciated

Regardless how sure the others in this thread are, it doesn't have to be a jellyfish from hydroids. It can also be introduced with artemia etc.

I have some collonial jellyfish in my tank. Was even able to made a frag of them but they are very fragile.

The medusa are even more fragile and die in a few days no matter what i did
