Jelly hitch hikers

[toothybugs]

It turns out my new rock gave me some jelly friends - I'm up to about a dozen of the little fellas at the moment, I spent the last half hour pipetting them out of my 40 and currently they're occupying a 20mL scintillation vial. I have a 5 gallon tank cleaned out awaiting these little guys. They're kinda neat, crystal clear bells with short tentacles that kick around and they scoot around pretty well for their size. I want to see if I can get them any bigger - right now I have a mix of sizes, bell diameters are maybe half a millimeter on the smaller ones up to a couple approaching 2mm.

I know I need minimal flow, for the time being I'm planning on using just a slow bubbler for water movement. Any tips on feeding them or other tips to maybe give them a chance? And no, I have no idea about species.

thats cool. do you have pics? no idea about feeding tho haha

I'd put up pics if I could but I doubt my camera would do this kind of shot - I'll see what I can do but no promises though.

BTW after sucking 5 gallons or so off my DT for this, I siphoned off another 5 jellies. Puts me somewhere around a dozen and a half or so

Edit: yea my old little point-n-shoot won't focus on them. Bummer. Maybe I need to bug my lady about getting a new camera.

Baby jelies are filter-feeders that are extremely delicate. Should best be kept in a tire-shaped tank so as not to get caught in the corners.
I had a few of these one time... They tend to end up pressed against the floor and unsuccessfully trying to swim, so they do need a very gentle flow across the floor to keep them in the current.
Look for clear polyps on your rock, those are polyps that the babies are budding off of.

Surprisingly the ones that hitchhike are a nuisence I've heard.. don't know how for same reasons as above but those that get them find them annoying in terms of getting rid of them..

They also give a painful sting.

Well I'm definitely getting more of them, every time I look in my DT I see 2, 3, maybe 6 of them floating around. My little 5 gal habitat has quite the community going. I did put in a bubbler, actually an old air-operated filter (all filter media removed, it's an open path top to bottom - no making jam out of my jellies!) and it's circulating the water nice and gentle. Also took a 1 cup measuring cup and filled it with sand to give a little filtration. I'm grabbing my zooplankton from the LFS tomorrow so this might actually work!

Any other thoughts, please chime in folks!

Could be hydroids.

Hydroid medusas?

 

[toothybugs]

Sure hope not. I've never seen these, or hydroids, before - some interwebs research was not promising.
