Description

Set up an aquarium for your own living sea creature pets! Prepare the salt water and then watch as small brine shrimp hatch from the included eggs, swim around, feed on the included food, and slowly grow larger. A fun, eight-page, full-color guide first explains how to set up the aquarium and hatch and care for the shrimp, as well as offers scientific info about these fascinating creatures and the ecosystems in our planet’s oceans. When properly cared for, the brine shrimp can live for months and even years, and the durable habitat tank can be used for bugs and other things afterward. Customize the tank with the included sea life stickers. The exclusive "Wow in the World" podcast content (accessed via a QR code in the guide) enhances the fun and learning. The kit also includes a magnifying glass to add to your collection of classic STEM tools. (Low maintenance and guaranteed to hatch; replacement eggs available if neccessary)

  • Definitely works when done right!!!
So at first I was very nervous to buy this for my 7year old son because of some of these bad reviews, BUT I would definitely recommend this product to anyone that's interested. We followed the directions and not even 48 hours after putting the eggs in, there are about 30 so far that have hatched!! I checked this morning and none were hatched but a few hours later there are so many swimming around!! Wish I could get a good enough video but they are so tiny when first hatched. Weird thing is the directions only want you to use half the eggs for the tank it comes with, so I used the other half in my own plastic container. The eggs I put in my own container are the ones that are hatching. NONE of the eggs In the tank this set came with have hatched yet. But I will do a update in about a week. A HUGE tip I would say is to place your tank in a window sill for daylight but NOT in direct sunlight. This is so interesting for adults and kids both!! UPDATE 1 DAY LATER LOL THERE ARE LIKE 1000 THAT HATCHED IN THE PLASTIC CONTAINER I PUT THE 2ND HALF IN!!!! SO COOL ... show more

  • SO CUTE
Great! They I started my sea monkeys in July and now it's October and I still had some! They were so much fun to take care of and entertaining watching them swim around.

  • BE PATIENT
BE VERY PATIENT. It says they hatch in 24-48 hours… it took 2 weeks for the first movement. It also says natural sunlight, but no direct sunlight… Direct sunlight actually made them hatch! Don’t give up!

Interesting learning toy for the little ones (1-5 years old) in my family. Got one for each family and mailed to them. Children LOVE getting mail. Fun, educational, and perfect size for mailing!

  • Read review.
This is great I’ve had them before years ago and LOVED THEM, Cool creatures, great first pet for someone looking for something simple, however this one they keep dying and I’ve done everything the instructions say to do I don’t know where I’m going wrong but they’ve died 3x and at this point I don’t know what to do. But it u manage to get this and they live “only a few will live and it’ll get bigger to where u can see it better” they are extremely cool to watch. My review is coming based on all of them dying each time I tried and no have no clue why. ... show more

  • They live forever!
They’re still alive ten months later and I still have a ton of food and materials. The kit is exactly as described, a good enough size, and has a small enough footprint to not take up much space. I recommend this kit for anyone considering a first pet for kids, just be aware the lid isn’t airtight, so store it where it won’t spill. ... show more
