GreenWaterFarm Moina Macrocopa Eggs (Water Flea) Live Fish Food for Hatching and Culture Suitable for Feed Betta Fish

Great quality eggs, hatch rate was high. I wasn't sure about this batch of eggs because I saw other reviews that indicated that their eggs didn't hatch or had low hatch rate. I just put the eggs in water 2 days ago and today I found an insane amount of babies in the water. Although I am unsure if they will grow to adulthood, these eggs definitely have a decent hatch rate and would be great for feeding fry.

Eggs hatched as expected. I used only about 1/3 of one vial in a 5 gallon bucket and had a lot of moina, in a population that did not crash right away. I am feeding them chlorella from a culture I started about 2 weeks before I started the moina. I have been keeping them for about 3 weeks and I feed my fish about 3 times per week. My fish - mostly tetras, rasboras and Corys love the live food!

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: 03/02/2023They 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.

The media could not be loaded. 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!

Very easy to hatch in two days. I’m beyond thrilled to see so many jumping daphnia in my little 1 gallon tank and began feeding my fish right away to control the population. I used declorinaed tap water and aquarium water and both times was successful with 1/2 of the vial each. I still have the other vial unused. An aquarium heater will help hatching much faster. Must have food after they hatch. I feel them yeast and spirulina.
