السي مونكي، كنت قد يأست ان يفقس البيض ولكن بعد مرور الايام فقس عن حيوانات مائية صغيرة وجميلة ولقد كبرت ومن ثم وضعت الأخرى بيضا آخر وفقس هو الآخر ولدي بعضا من الأمهات والكثير من الأطفال 😀 تجربة مثيرة ورائعة وتنصح بالشراء

Missing parts
Ordered this item a while ago, took many days to get delivered and when we opened it we saw that the sachet with the sea monkeys were missing. Given the time we lost, my son missed his class experiment

Bought them and was disappointed that after 2 days the 7 that hatched all seemed to have died. We left it alone and a few days later there were 2... then 4... nine days later and I just counted 21! Four are huge! If yours die right away, don't just give up. Poke any eggs along the surface back down and wait! My kids love them. If you have issues ordering more food. Yeast and Spirulina can be used :) They love algae

Mine have been going great! I’ve had them for about a month now. I think I’ve got a fairly solid colony of about 15-20 shrimp. There’s just a lot you have to keep in mind if you want them to hatch; they’re not as easy as they seem. Make sure they’re kept in a warm room. I keep mine near a window, which promotes algae growth (good for oxygen and food!). I also stir my tank with a spoon twice a day, about 15 rotations per stirring session. This helps distribute oxygen throughout the tank. For feeding, I see how “dirty” my tank is whenever I stir. I also check the lines that run down the shrimps’ backs - if they’re not visible, they’re hungry. Using this method, I’d say I feed them every ~4 days. Also, be sure to top up the tank when the water gets low as well, because it restores the salt in the tank (prevents bacteria). I’ve just been using bottled water. I’d also buy some aquarium salt if you wanna be EXTRA safe, but I wouldn’t use it unless a bacterial outbreak occurs. Lastly, don’t panic if you notice the babies dying at the start. You’ll probably get a ton of babies (‘squirts’ I like to call them), but not all will make it to adulthood. The majority won’t. That’s just how it is, so don’t be too rough on yourself! All in all, great kit. You just need to know how to use it. Make sure you keep that tank warm!
