## Description

desertcart.com: GreenWaterFarm Moina Macrocopa Eggs (Water Flea) Live Fish Food for Hatching and Culture Suitable for Feed Betta Fish : Pet Supplies

Review: Read This Before You Try! I Got a Successful Hatch in Under 24 Hours - I saw a few reviews saying these eggs didn’t hatch, but I can confirm: they absolutely do hatch if you follow the right setup. I had Moina swimming around in less than 24 hours! Please read this before you try—it will save you frustration and wasted eggs: 1. Use clean, dechlorinated tap water. Avoid pure RO or distilled water—they lack essential minerals. Tap water is perfect unless your water is from a well or has very high pH. If your water is too alkaline (above ~8.5), you may have trouble hatching. 2. Water depth: Keep water at about 3–4 inches deep. Shallow water improves light penetration and oxygen exchange. 3. Light is critical: Place the container near a window with good indirect sunlight, or use a daylight-spectrum bulb (white light) about 3–4 inches above the container. Aim for 12–16 hours of light daily. I used an old aquarium white LED light. Yellow light is not as good. 4. Temperature: Around 75–85°F works best. Room temperature worked well for me. 5. Let the eggs float: Floating is normal and helpful! Don’t try to sink them. The eggs hatch best near the surface with light and warmth. 6. No aeration needed: I didn’t use any air pump or aeration, and they still hatched fine. Aeration might help, but it’s optional. 7. Don’t overdo the eggs! I used an entire capsule because of some other reviews, and it was way too much. I wish I had not done that. Half of one capsule is plenty to start a good culture. 8. Be patient: Hatch time is usually 24–72 hours, but I saw mine start moving in under 24! 9. Feed once they hatch: Use chlorella powder or pure spirulina powder, dissolved in water. Start with a very small amount—just enough to lightly cloud the water. Don’t overfeed! I’m really happy with the results. If you follow these steps, you should get a great hatch too. Don’t let the negative reviews discourage you!
Review: UPDATE: 2 Weeks and Nothing Hatched -- Day 11 and nothing has hatched - It's day 11 and nothing has hatched, at all. I used the capsules between 4 containers. I wanted to experiment and see which hatched out best. 2 Reverse Osmosis and 2 tap water (well water with a whole home filter system and treated with tap water conditioner). 1 R/O and 1 tap were under a heat light (water temp 82°F) and the other 2 were room temperature (72-75°F). All containers are under a grow light (with my plants). NOTHING, absolutely NOTHING has hatched. When day 14 rolls around without anything hatching, I'm packing up the empty capsules and sending them back for a refund. UPDATE: It is now day 14 and NOTHING has hatched. I just noticed that this item isn't returnable. So, I'm out $15 (taxes included). I just sent an email to Green Water Farm and I'll update if they reply. UPDATE: 03/02/2023 They finally started hatching about 2 weeks ago, so it took about 4 weeks to hatch. Not everything, but enough to start a culture if they survive. The ones that hatched were in a small bowl with R/O water at room temperature around 72°F (no heat light). I took advice from an old forum thread from someone who cultures them on a large scale and have been feeding them Sweet Potato baby food. About 1 tablespoon into a bottle of water (a regular sized drinking water bottle) and shake it up. I put about a tablespoon of that mix into the culture every day. They actually swarm to it. I also dump it into my daphnia cultures and they're populations are booming. I mix new food every day, and toss the baby food after a few days. I also top off the bowl with water from one of my Daphnia cultures. Every few days, I carefully siphon out 1/4 water with a turkey baster and scrutinize it for baby Moina and replace the water with fresh R/O water. It'll take a hour to do, lol. Once the babies get a little bigger, I'll transfer them into a larger container with an air pump--no stone--just air line with a regulator turned down to a couple of bubbles per second. I also would like to thank Sprite from Green Water Farms. I reached out to tell them that nothing had hatched and he sent me a new pack of eggs. I'll keep them in the fridge until I need to hatch them.

I would like to suggest you order fairy shrimp eggs instead of Moina because it's small than Moina. So it's suitable for baby betta than Moina

However, Fairy shrimp eggs out of stock on FBA now.
it's will available on FBA in 10 days.

### ⭐⭐⭐⭐⭐ These actually work. Don't hesitate to buy.
*by J***E on November 17, 2025*

Im actually very impressed. I spent far more than the $15 on live cultures being delivered to the glue with postage and everything. I was having an issue getting my daphnia numbers up so I figured I'd give this a try. After adding the eggs to my currently running culture I was please to see hundreds of hatchling daphnia swimming around. It only takes 3 days. With these out there I will never pay the expense of a living culture. I'll just add these to my tank and go from there. I was skeptical but this came out awesome. Will buy again. If your breeding tropical fish, just add these a few days before your expect to need fry food. Smaller than baby brine shrimp and just what is needed for tiny fry.
