Product Description

Small Sphere EcoSphere (4" diameter) with turntable base. This fascinating enclosed world contains 3 to 4 marine shrimp, algae and micro-organisms. Made from hand blown glass, each EcoSphere is a completely enclosed, self-sustaining little world. The EcoSphere only needs indirect light and comfortable room temperature (between 60F and 80F.) The EcoSphere works on the basis that a closed system recycles its nutrients and does not produce excess waste. The shrimp consume the algae and micro-organisms and they, in turn, break down the shrimp waste. External light, either artificial or natural, keeps the algae growing. There is no feeding or water changes required.

WARNING:

CHOKING HAZARD -- Small parts. Not for children under 3 yrs.
CHOKING HAZARD -- WARNING: This product contains small magnets. Swallowed magnets can stick together across intestines causing serious infections and death. Seek immediate medical attention if magnets are swallowed or inhaled.

Important information

Directions

The EcoSphere only needs indirect light and comfortable room temperature (between 60 and 80 Fahrenheit)

Legal Disclaimer

Due to the live nature of the product EcoSpheres only ship to the continental USA, they cannot be shipped to Alaska, Hawaii, AFO/FPO, PO boxes, nor Internationally due to export/import requirements.

Update: shrimp are molting - my shrimp are healthy and active
Update: Had these for a few months now. Adding a picture to show that mine are molting, so I guess that means they’re growing? Pictured is one molting, can’t get a good picture of the other ones old shell that finished molting alreadyOriginal:i've seen quite a reviews stating these shrimp are slowly starving themselves to death. i would disagree, in the month i've had my sphere they regularly regenerate their waste line, and it becomes clear after they have a little shrimp bowel movement.i am slightly concerned one shrimp is unhappy with the environment. two are red, and the third is red when i remove the cover or reintroduce light, but goes pale an hour or two later. unsure if this is just a reaction to UV light as well.IMO - as long as you take care of these, the shrimp seem to be no more miserable than fish in an aquarium.i will provide an update if my shrimp die or appear to be in poor health.
Thank you for your feedback

5.0 out of 5 stars Love it! Worth every penny!
Reviewed in the United States on July 11, 2022
I love my shrimps so much! They all have names. I keep them on my desk at work and spend a large part of the day peeking in to see what they are up to. They never cease to entertain me. They are so cute and fun and it brightens the day for my friends and family when they receive my constant pictures and videos of the shrimps. It’s a great little world they live inside their ecosystem and they are easy to maintain, just follow the directions to place them in the correct area of ur home or office and then they just take care of themselves. I just love them.

Original:
i've seen quite a reviews stating these shrimp are slowly starving themselves to death. i would disagree, in the month i've had my sphere they regularly regenerate their waste line, and it becomes clear after they have a little shrimp bowel movement.

i am slightly concerned one shrimp is unhappy with the environment. two are red, and the third is red when i remove the cover or reintroduce light, but goes pale an hour or two later. unsure if this is just a reaction to UV light as well.
