Any Jellyfish keepers here?

[CP aquatic]

I have been thinking about and researching jellies for a long time now. I was thinking of building a tank like the one in the link out of a 55 gallon. Anyone else ever try anything like it? Any advice on general care of jellies?

I saw this the other day. I don't know if I would trust their claims however.

The Darwin Tank

Seems a little too basic to me in all.

At least its affordable...$1700!?!?!?!:eek2:

Right?!! There was half a dozen of these tanks at MACNA.. All of them using the same basic design, but costing $300-$400 and under 5 gallons.

Do those set ups come with chillers

I've taken care of a couple moon jelly tanks in public aquariums, I will say the biggest issue is always flow. You need to make sure the jellies and food stay in suspension, but without having so much flow that they get shredded. We always used Kreisel setups.

Also, the tank will need to be chilled for moon jellies and you'll need a acceptable food source as well (we always fed out enriched brine shrimp nauplii).

Lastly, you need to make sure you can avoid air bubbles in the system. If the bubbles get caught in the bell of the jelly, it will "burn" a hole straight through.

Hope that helps!

Hmm didn't know about the air bubbles.. Thanks for the info! as for those all in one tanks they don't come with chillers

Most of us seem to like to change things up in our tanks with types of fish, rock work, coral placement, etc. I think I would love a jellyfish tank but eventually get bored of just the same ole thing. If it was in say a reception area of a business, the conversation with the customers would maybe keep the interest up. I'd think about whether or not you are the type that it would hold your interest long term.

I have had good success with this tank. It is approximately 30 Gallons.

^This is just about all you need to know bout moon jelly care. I work at a public aquarium where we grow/maintain a handful of temperate jelly species. For enclosures we use kreisels or pseudokreisels (tanks with plastic inserted into the corners to round them out, making a "U" shaped trough) equipped with spraybars to keep flow even. It takes some adjustment so that your animals aren't flying around the tank or being cheese-grated through the mesh outlet.

I recommend you keep moon jellies as they are quite easy to care for and areforgiving in terms of hardiness- plus they can't sting you as human skin is too thick for them.

We feed our moon jellies enriched brine nauplii as well. works great. If that's not an option for you, frozen brine nauplii/rotifers would be a suitable replacement, but I would recommend target feeding the jellies if you're going to take that route.

As far as temperature, moon jellies are tough but do best in cooler water (we keep ours at 55F-58F) but they should do fine in anything 70F or lower.

Bubbles are a problem for jellies as stated. Bubbles caught on their underside in their stomachs will work their way up through the bell of the jelly and leave a hole. Usually bubbles occur when feeding with a baster, as some air can be pushed out into the tank. Thankfully moon jellies are clear, so bubbles are easy to see and can be removed by turning the jelly over and massaging the stomach to push the bubble out. What you really need to watch out for is microbubbles; make sure there are none as you will probably not be able to catch them and will find your jellies perforated.

This particular Kickstarter is really popular - with units already being made and reviewed. Whether or not it works, you can bet you'll see a TON of used ones very quickly as the novelty fades: https://www.kickstarter.com/projects/jellyfishart/jellyfish-aquarium
