I bought one of these EcoSpheres back in 1999 for my dad as a Christmas present (yes, 12 years ago!), and it is still going strong in 2011! Algae, shrimp, everything... When I say "with the right care" in the review title, don't mistake that to mean it really requires much of any -but it surely helps that it is kept in the right light (the algae grows with more light & shrinks with less) and the right temperature.
The same results obviously cannot be guaranteed, but the one I bought has been well worth every penny and shows no signs of stopping -so it is obviously possible. Very cool product...
**UPDATE: It's now a year and a half after I wrote the initial review and the shrimp is still kickin'... so that is now 13.5 years that it's been going strong. Not too bad.
This is a review copied over from the teardrop shape of the same thing. I realize this will upset many long term, happy owners of the sphere. This is NOT aimed at owners at all. It is merely meant as an additional bit of research information on a very popular retail item. I will attempt to present information that you are free to verify or prove false via your own research.
Original review:
I received one of these as a gift about three years ago. I am a hard core believer in "research what you must care for" as once you take a living thing in and state "I shall care for it" you are responsible for a life. Or several, in this case. Rather quickly, I learned that these shrimp are "Halocaridina rubra" AKA "Opae Ula" AKA "Hawaiian Red Shrimp". They are found in small wild pools in the lava rock all over Hawaii. Rather disturbingly, their habitat has been reduced by roughly 90%! Yet people still continue to collect them from the wild. As of now, I have yet to hear a confirmation that the Ecosphere company is, in fact, captive breeding these creatures. If they are, in fact, wild catching these, even from a pool on their own property that they help to maintain, this may have a rather strenuous impact on what is left of the population of these shrimp, given the number of these spheres and "BYOES" they ship out annually.
The sad fact is that the only people truly giving a representation on the current quantity of these available in the wild are the people who are catching them in order to sell to the general public--and of course, it is in their best interest to state that they are plentiful in the wild, as their livelihood depends on it. Granted, this is pure extrapolation, but I think it is, at the very least, a point worthy of consideration before you purchase one of these kits.
These shrimp are slow breeders with small clutch sizes, and a rather high "infant mortality" so to speak. In short, they are a species which much be protected when possible, and encouraged to breed-be it in captivity or in the wild, in the hopes of creating a sustainable population that our children and our children's children will be able to enjoy.
Keep in mind when purchasing an ecosphere that, regardless of all other facts, the very limited environment dramatically discourages breeding and prevents perpetuation of a species that is currently undetermined in status.
Now, skipping the biology and ecology lesson, and on to the ecosphere itself.... As I studied the limited literature and information available on these shrimp, I learned that although there is the odd ecosphere which reaches just that right balance of diatoms, algae, bacteria, shrimp, etc., the vast majority are nutrient starved, and the ecology inside of them, at the microscopic level, becomes damaged and even destroyed. Then you are left with a couple of shrimp that are incredibly hardy, attempting to live in water that is high in ammonia, nitrites, and/or nitrates, with little to no oxygen for breathing, and eating forms of algae that are in fact, not at all nutritious for them. Because these insignificant seeming little creatures have adapted to such an incredible fluctuation of natural habitat in the wild, they are able to withstand starvation for months and even years.
Look at it this way: The average Opae Ula shrimp life span is roughly ten years, with some living upward of 20. Ecosphere happily informs you in the informative brochure that if you take care of them well (ie: set them in the appropriate light and temperature) they will average a whole 2-3 years! So.....1/3rd of their expected lifespan......
Not so good, in all honesty.
The instructions then go on to explain that on occasion customers excitedly announce their shrimp going 8-20+ years. Which really, that's fantastic! But this is the exception, not the rule.
These shrimp are, slowly but surely, starving inside of these closed systems. If the correct bacteria and algae do not grow (and often they do not) then these poor little creatures will shrink a small bit each time they moult their exoskeleton. According to several sources I have read, they will, in fact, consume themselves at a very slow and painful rate.
Again, not to say that some spheres will not survive 20 years plus ND prove this wrong, but, sadly, the vast majority of spheres are going to slowly decline, taking the living denizens inside down with it.
All of this said, I received my little ecosphere, containing four opae ula shrimp, and I chose to believe that I would balance the lighting and the temperature perfectly, since I honestly couldn't figure out how to get the shrimp out. Fast forward two years, and my first shrimp dies. What a wake up call. I felt terrible. All the shrimp were on the small side when I received them, as I had been hoping for closer to the ten year mark from these fellas. I immediately got online once more and researched all that I could. This time I learned how to remove the plug, and so I did. The three remaining shrimp were decanted carefully into a 2.5 gallon cube aquarium that was carefully balanced to match the specific gravity of the water inside the sphere, with a small airstone and an LED light. I will state that when I tested the ammonia, nitrite, and nitrate of the water inside of the previously sealed sphere, I was absolutely appalled. I have zebra danios that couldn't have lasted an hour in that water.
In any even, I started off with only the water from the ecosphere, and daily added about half an ounce of the newly mixed sea water, in an attempt to not shock these delicate little creatures. Now that everyone is happily adjusted, I can monitor the amount of food available, do roughly one 50% water change a year, and care for these fascinating little animals interactively, rather than passively. I can respond to their needs and keep a close eye on the quality of their water, and thus, their life. Low and behold, my three shrimp have become roughly ten shrimp in less than a year (exact counts are tough, as they now have many hiding places and I am never sure that some aren't tucked away and hiding! Far more natural and comforting to them than complete exposure as they are subjected to in the spheres!). In fact, I am almost certain that those little reddish jiggy looking things that I noticed in the tank yesterday are, (I hope), more larvae.
Please, I encourage potential owners of ecospheres to research these shrimp and learn what you can before you purchase. If you still choose to purchase them, fine! But please, do make an informed decision.
In all honesty, I have to seriously wonder about the honesty of any company that simply states that they are giving you "ocean shrimp" and does not provide you with a latin species name to look up information and a natural history on the organism. Particularly when it is a company that claims to be encouraging an awareness of ecology, who is selling a species that is so vulnerable in the wild as these little fellows. If they were truly a company encouraging the thoughtful preservation of our ecology, it seems to me as though they would be attempting to inform new owners of as many facts as possible about their new pets; not hide what they are to prevent you from purchasing them cheaper elsewhere. (or whatever reason they have for not telling you exactly what kind of shrimp they are).
I wish potential owners the best of luck with their fascinating new aquatic denizens, regardless of how you choose to get your hands on them and welcome them into your home, and I sincerely hope you give these thoughts some consideration.
Cheers, and happy shrimping!
Buy EcoSphere Closed Aquatic Ecosystem, Sphere Now
Having always been fascinated by small shiny objects, and being an ecologist, I was always attracted to the EcoSphere and like setups. After letting it hang on my Amazon Wishlist forever, I finally decided to pull the trigger and buy one. It showed up in a special mailing box in a couple of days (oh, and buy it direct from Amazon, don't pay the $20 shipping stinger from other vendors). It only took a few minutes to confirm that this is a really cool product. Our sphere has three shrimp in it, and they're plenty active. The sphere needs indirect light, and the little direction card tells you how to keep track of the light situation ... if your plant is shrinking, give it more light ... if it is overgrowing and the sphere is getting a lot of algae on the inside, reduce the light. The direction card has a magnet on it and there are a couple of magnet bits in the sphere; you put the magnet to the outside of the sphere and the inner magnet is attracted to it, and then you wipe around the outside to clean the inside (but this is only if you over-illuminate). By the way, the life expectancy is supposedly around 2 3 years, and EcoSphere also has a nice replacement/recharge program. One final note, to elevate the sphere on my desk, I took a good-looking coffee cup, inverted it, put some clear silicone on it, and stuck the sphere to it. Looks real nice and now my shrimp buddies can get a better view of my distinguished countenance and me theirs ... or maybe I am scaring the heck out of them. Hmmm...

I have been looking at these, and considering them for years now. Never could bite the bullet and buy one though. I got a gift card for Christmas, and thought now would be the perfect opportunity.
Honestly, for the price, I was expecting something larger. If nothing more than just a larger sphere with more water to make it feel more substantial. It is approximately the size of a softball. I will try to update the review after I have had it a few weeks. My plan is to keep it on my office desk. I can't seem to keep a plant alive. Hopefully, I have better luck with this.
I didn't see it posted anywhere before purchasing, but be warned. You have to get overnight shipping. Obviously, they want to make sure it isn't sitting in some delivery truck in the hot/cold for an extended period of time. For me that added $20 to the price. Basically, my gift card ended up paying for shipping.

I wasn't quite sure what to expect when I ordered this as a Christmas gift for my 8 year old. But I was VERY pleasantly surprised! It's way cool, and exactly as advertised. Our ball has 5 shrimp, probably around 3/8" long. Very visible, the water is clean, and it's just incredibly awesome. I'm tempted to buy another one for myself to take to work with me.

I looked and looked and looked for a travel kennel that would be tall enough for our Great Dane. They're hard to come by! Hauling his wire kennel with us just isn't feasible it's huge. This was plenty tall and easy to set up (once we realized the poles are in a pouch in the bottom). I like that he can see what's going on outside the kennel (unlike some that just have a small mesh window). The first time we used it, we took our dog to a friend's cabin. It did the job. He did try to dig his way out of the front and there's a little wear and tear. I could see where that would be a problem if your dog really wanted out but no travel kennel is going to withstand a dog with separation anxiety or severe boredom.
