jellyfish

[Boggnials]

i was wondering if anyone has kept a jellyfish. if so what is entailed in keeping pne of them.

I had a batch purely by accident! )
Dont know where they came from or what they were. I guess they came in on live rock.
Very tiny and seemed newly hatched or something, lost the lot im afraid )

The problem with these creatures is that they will get sucked into powerheads and killed. A saltwater tank needs powerheads for circulation, helping the lierock with filtration and of course oxygenisation. Jellyfish are weak swimmers and can eaily get sucked into a head or blown against the rocks and get ripped or damaged. This will soon lead to their deaths )

Unless you have a speciality tank that caters only for jellyfish then i would not recomend them. They require highly specialised care IMO

I don't know if it's even possible. Jellyfish would be harder than most other things by their nature. They mostly go with currents and grab at food randomly with their tentacles. They'd be hard to keep and harder to feed.

I must admit i have never heard of any success with these things. Even the National marine aquarium near me donest have any on display.

I have read about people keeping tanks with only LR for years and year. Adding nothing. Since hydroids are related to jellyfish, i guess these evolve into jellies over time. I think they called them god-tanks or something crazy.

Ooo, "God-Tanks" sound fun! I guess you could consider any aquarium a "god tank" tho.. They are pretty much totally at our mercy I try to be a kind and compassionate God.. Although a bit lazy at times

I know what you mean. I hope our fish don't resent us!!!

A shop I worked in at one time was able to order a small jelly. We kept it in a small tank (10-15 gal), several chunks of live rock, filtered by external power filter. As was stated, the jellies kind of float with the current, so we built up a pile of small pieces of live rock (rubble pieces) around the filter intake so that it would not get sucked up. This particular jelly would feed on small plankton, so the tank was dosed several times a day with phytoplankton. Jelly did quite well for a few months, but most of the time it would rest on the bottom of tank, this may have been its nature.

They are interesting to see, but I don't think I would recommend jellies for the average home aquarium, even if you were able to give it it's own tank.

I've never heard of this particular jellyfish but apparently it's one you can keep in an aquarium.

Upside Down Jellyfish

Minimum Tank Size: 30 gallons
Care Level: Expert Only
Tank Conditions: 72-78°F; sg 1.023-1.025; pH 8.1-8.4; dKH 8-12
Temperament: Peaceful
Max. Size In Aquarium: Up to 8"
Reef Compatible: No
Caution: Venomous
Diet: Filter Feeder, Carnivore
Origin: Caribbean, Indo-Pacific
Family: Cassiopeidae

The Upside Down Jellyfish, also called the Cassiopeia Jellyfish, is so named because its flattened bell (head) rests on the bottom. It extends its frilly tentacles up into the water column where they capture planktonic food and absorb light that is used by photosynthetic algae that are housed in its body.

It also prefers a wide sandy bottom to the aquarium and requires high intensity light for photosynthesis to occur. It will not tolerate copper or high nitrates in the water, and since its body is composed of 95 to 98% water, sudden changes in salinity or pH can have radical consequences.

Its sting is mildly toxic; humans very rarely notice the sting. Care should still be taken though when handling it or while doing maintenance on the aquarium.

It will require daily supplemental feeding with zooplankton substitutes.

Please note: We guarantee that ALL aquaria species we offer will arrive alive and in good condition. However, because of the increased level of care required for this particular species, it has been designated as "Expert Only," ® and we cannot guarantee it after arrival. As an Expert Only species, we recommend that only the expert marine aquarist, zoo, or research institution should purchase this species.

Approximate Purchase Size: 1-1/2" to 3"

I don't know if it is possible to keep one in a home aquarium... but the Monterey Bay aquarium houses many different species of jellyfish quite successfully. They are a BEAUTIFUL sight!

The aquarium in Chattanooga TN. has a jellyfish display as well. Beautiful creatures... Not sure I would want them in my tank, got stung several times surfing..
