Jelly Fish

[happyvac]

My friend and I were talking a couple days ago, and somehow I brought up saltwater fish-keeping. Then he said that the one thing he'd want would be a tank of pink jellyfish . I understand that this is really next to impossible, but, out of curiousity, how would you keep some of these? I remember seeing a tank of them and it couldn't have been more than 300 gallons :thinking:

I dont know, but ive seen some really cool looking jelly fish in some of the aquariums here

They have to be housed in a round tank, no corners. This was brought up several weeks ago. Maybe even a chiller installed? That, I'm not to sure on but the cylindrical (sp) tank is the only way they can survive.

Yup, they need a very specialized tank which I almost never can spell - a Kreisel tank. It has a particular type of flow and is basically circular. Many will need a chiller, and they actually require a fair bit of care. It is not easy to clean the tanks and they require a pretty good amount of food.

That's what I told my friend...cylindrical tank with a low flow and chiller. So is it even possible in a home aquarium?

Well actually the shape of a kriesel is fairly easy to DIY, but there are some very tough parts of it..and you also have to have a rather large system for most jellies,a dn their diet is hard to master.

what about the upside-down jellyfish? I was reading about them for a while the other day... they still need a very specialized tank as far as temp and food goes, but wouldn't the flow issue be solved since they generally rest on the substrate?

one of my lfs has succesfully kept a upside jelly in a tank with mangroves and flame scallops. sort of a mangrove swamp theme. which is their natural habitat because i pretty much grew up living next to those jellies in miami. also their diet is pretty much photosynthetic.

They still commonly get sucked up onto powerheads and filters. I agree with the above...in a species tank with mangroves and such - their natural habitat - it can be done. But our home tanks where we put in a little bit of anything, I do not recommend it.

oooooh LOL Did you know we are in the same phylum as tunicates
(according to the old classification system). Shows you how broad phylums realy are.

 

[nereef]

yeah, actually i was looking up sea apples the other day and ran across that. hard to believe something like that has a spinal column. they just look like lumps to me lol.

 

[celacanthr]

Well actually they (adults) don't, but the larvae do. Actually yes their are some tunicaes that keep their notocord throughout their whole life. Why did a tunicate come up on a search for a tunicate?

sure makes things tough for classifying animals. you're right though, the larvael stage is always the one that is considered.
