im hoping that someone out there in this site will have good information for me. im undergoing a huge project with little money for my gf. you see we both are in love with jellyfish and i would like a tank in my house but the thing is all the ones i've located on the internet are way to expensive for what they are, and i believe i can build one for cheaper but i dont know the first thing about the equipment, or the materials i would need for the project. Any advise is good advise.

thanks you

hmmm, jellyfish huh? I think I read somewhere in this forum about how difficult and tedious it is to keep jellyfish, because everything has to be perfect...but then again, if there are tanks for it, there must be a way! I wish I could help, and good luck!

To be honest, I don't think anyone here has had much experience with a big saltwater project like that. I would highly recommend www.monsterfishkeepers.com since their members seem to keep some of the more difficult/exotic varieties of saltwater fish. They also have detailed plans on the construction of large aquariums. And like we've said before, make sure you are prepared for what is to come. Jellyfish are a lot of work, and that's an understatement.

I think that it's going to be impossible to do a jellyfish tank for cheap.

You pretty much need a tank with NO corners at all.........not to mention all the maintenance and stuff.....

I'd be very cautious trying to build your own system if you don't have prior experience or have a friend who has experience to personally help you. Could end up being a disaster. Just be sure to research, research, and then research some more.

all of the actual "jellyfish" tanks ive seen are either spheres or circular. that would be difficult to do.

It is however good info, and something that should be noted is that Jellyfish do need to be kept in a cylindrical aquarium. Corners are deadly to Jellyfish since they will very likely get stuck there.

Oooo old thread, but still a thread in itself.

I'd love a jelly aquarium, but I think that instead of having a completely cylindrical tank, which would be hard to do and expensive, couldn't you just block up the corners with some excessive amounts of tank sealent? Wouldn't that be cheaper than a huge cylindrical tank?

It would be pretty cool though, a huge round tank. Jelly fish aren't that exciting, and I think tank maintenence would be painful, but it would still be a really cool tank.

You would need more sealent than is practical. The only sane way to do a Jelly tank is to do a cylindircal tank.

yah i have seen some really cool ones that are giant spheres about 6' across.

Ya I guess so, oh well.

I'd assume a tank like that would be hard to make, and probably very breakable, and super expensive. I've never seen anybody with a jelly fish tank before, but I really want to. I don't think I'd ever want one though..now that I realise how difficult tank maintence would be in a huge cylindrical/ spherical tank with poisonous jellies...and what if they got sucked up the gravel vac? Would they just compress themselves and squeeze all the way down the tubing?

I read an article recently on how Jellies are becoming more popular. The greatest challenge is having a steady and consistent current all throughout the tank. Something about the way they are suspended in the water. I would be wary about building one yourself, although hopefully if they keep growing in popularity the existing ones will become more affordable.

old topic but in case anybody's interested, it'd be pretty easy to make the tank itself if you have some fiberglassing/woodworking skill. 3/4 cylinder of fiberglass with a flat acrylic or glass viewing window.

Since jellies live in the open sea mostly, you'd need very good filtration. A public aquarium I went to had plumming under a grate that was under a moon jelly tank. The good thing about marine jellies living in the open water is that you will not need any live rock.
There were these tiny jellies at that public aquarium which were kept in a rectangular tank. They looked very fragile though.
Moon jellies are harmless to humans, but they get huge.
Feeding would also be expensive, as jellies feed off of live plankton.
I've also heard that jellies only live a few months, so you might not find it worth the time and maintenance.
I don't think you could do a jelly tank on a budget, but if you really want to you should try and find a saltwater specialty shop and ask them.

Here is where you might get relief; There are freshwater jellyfish, and it might be worth your time to research those and ask your lfs about them.
Here is an AC article on freshwater jellies http://www.aquaticcommunity.com/jellyfish/freshwater.php

Well the freshwater jellyfish aren´t really jellyfish but they are very similar to jellyfish.


It is possible to build tanks for small jellyfish species (1. max 2 inches across)y ourself for a reasonable sum using large cylyndrical glas vases or similar and glas bowls. However it is not easy and it is easy to break the materials while working on them. I could write an article on it if there is interest.

The idea of keeping jellyfish is fascinating. I would very much enjoy reading an article about the process!

i'd also like an article on keeping fresh water "jellyfish" very much. i am quite intrigued about the subject,

A circular jellyfish tank would look like a lava lamp!

The box jellyfish is actually the msot poisonous animal on the planet.

I would think you would need to find something more similar to a ball, cut that into 8 sections that were all large enough to be half the height of the tank. even the way you have it the tank still technically has corners to it. I don't know anything about it personally, but i assume when it is stressed that there must be no corners or rough edges i imagine that means none at all. The tanks I've actually seen with jellies at my local aquarium (not my LFS) have absolutely no corners, including at the top and bottoms. maybe you could find a large acrylic tube? Although i have no clue where.

The filtration systems at my local aquarium also appear to have the filtration built into the bottom, and use a very fine grate so that there is absolutely nothing the jellies can bump into or get stuck on, they aren't exactly the smartest of creatures :hmm3grin2orange:

Here's a link to their jelly site, most likely doesn't have any, but might have some useful info for you http://www.montereybayaquarium.org/efc/efc_se/se_jla.asp

Here (http://www.midwatersystems.com/) are some tanks. I highly doubt you'll end up buying one.

correct, I won't. Not very interested in jellies at all. They're cool, the tanks and jellies, but whew they're pretty dang pricey. I could go see them locally any time i like too, lifetime member of that aquarium i linked :)

and i guess i was wrong, there are still some sharp edges on those tanks, i guess it's just about not allowing the jelly to get stuck in an actual corner.

the aquariums in that link remind me of washing machines :hmm3grin2orange:

anyways Jellyfish seem pretty boring to keep so Im just going to stick to regular reefs.

lobsternoob
02-04-2009, 07:53 AM
I'm totally agreeing Miltonic, I'd love a nice reef tank rather than a jelly tank. We all have our own tastes though, but jellies seem dang hard to keep from what I know (very little). I don't find them boring, they are interesting, but the effort involved in keeping them just sounds somewhat insane. I'm going to try and talk to one of the caretakers of the MBA jelly tanks in the next few days, just to find out what it really takes to keep them, and which jellies are realistic for home keeping.

Hopefully I will come back from that with some info for you AABatteries, rather than just sounding like I am being discouraging towards what i think is a pretty cool idea. I really do not want to discourage any hobbyist, just really really doubt they are anything but difficult to keep.

Hi guys I am new here coz of this thread... Very old thread and trying to get it alive... Please refer to the pic down here for my DIYed kreisel tank... I have proper as built drawing if anyone need it... Its still a on goin project as there is still no jellies in the tank yet... Thanks for the movie 7 pounds as it motivate me into this... enjoy...

And this is the type of jellies I am putting in hopefully soon enough

Anyone interested? hardly find someone who interested and feel so lonely...:scry:
Just wish to have someone to discuss bout this awesome species

Almost forgotten heres how the tank filteration works

that's pretty cool, really looks like you've put a lot of work into it. Where did you find the jellies?

That's quite an interesting tank design. I had heard that they required round tanks, I had assumed that the tank would have to by cylindrical vertically, not horizontally. Just goes to show that you learn something new here all the time! Good luck with it and post pictures when you've got your jelly fish. You may just inspire some other folks!

Actually I used up 2 whole evening (6pm-12am) for the tank building and 1 for testing... Not too hard indeed... Its actually even more headache to source a round acrylic...
I am getting the jellies from the beach nearest to place I stay which will take bout 1.5 hours driving... That will be a seanettles


That is very a impressive tank you are building!

I am working on the tank stand and starting to cycle the tank before the first batch of jellies in... Hope will see something in my tank within this 2 weeks time...

You're right that they need to be cylindrical type but both vertical and horizontal type have pros and cons after my research... In 7 pounds, its vertical one... But a true Kreisel is horizontal... This is just a pilot project and if it successful, I will built a larger scale one probably a 3' cylinder as a display tank in my house... cant wait for that day to come :hmm3grin2orange:
