I was excited to get moina for my fry, since I have a thriving colony of daphnia that I feed regularly to all my aquariums. I regularly hatch brine shrimp as well for variety for all the fish. My first container had zero hatch. I will split the next one and try hatching some in green water, some with heat as I read in another review. Not sure about following directions on box again. Will give it a couple of weeksUPDATE- second try in green water was excellent. Takes longer to hatch than expected. I would buy again, but only put the eggs in green water to hatch. I did not use heat either time.

I used about 1/3 of a vial and had full tank of tiny crustaceans in couple of weeks. They happily multiply while fed yeast or spirulina powder. Fish gets very excited catching them one by one.

Takes more time than I thought. Quality is not what I expected but all seems well. Really tiny critters so far waiting to see adult size.

All eggs hatched within 24 hours in aquarium water. A light was used on one jar and none on the other, both hatched around the same time. No airstone needed

This tank is over a year old and it's been a stable tank with no new introductions of fish, plants or anything it is also the only tank I have. After following the instructions provided I ended up with hardly any actually hatching in a small container in my tank that would allow them to grow and I could feed them separately from the rest of the tank yet I hardly got any to hatch from both provided canisters.Once I noted they were unlikely to produce many I just released what I had into the tank to allow them to be eaten and perhaps survive.Now here I suddenly have a bloom of hydra forcing me to perform extra actions to stop them before they get out of hand. Would not suggest getting them if your tank is stable and doesn't have any hydra.

I put these in water yesterday afternoon and tonight I see lots of them have already hatched! I filled a small 1 gallon acrylic tank with distilled water and am using a nano heater set to 78°F. This was a tank I’d just used to grow rotifera in and didn’t scrub clean so the sides still had biofilm and remnants of yeast and chlorella. I saw the video of the guy who trapped the cysts underwater and complained they didn’t hatch. Don’t do that. They float. If any get stuck on the side of the tank just hose them off with a pipette. Idk how beneficial it was but I did initially only fill the tank 1/3 full and then added more water in 2 more stages 2 hours apart as I’d read that helps the hatch rate.

I’ve been using these eggs to grow diverse microfauna for my fish tank and have a fairly good success rate with these eggs hatching. Heat, light and oxygen are the key. I use a small glass jar, put about half the vile/pill of eggs in, cover with an inch or two of warm tap water and put the lid on, place on a warm pad used for seeding plants and make sure they are near a light source (window/lamp/tank etc). Not too much water is needed because the heating pad is warming the jar from the bottom and too much water will be harder to keep warm as well as to oxygenate. Swirl the jar a few times a day, you should see bubbles. Once they hatch drop in a small amount of food like fish or algae pellets. Mine usually hatch in 1-3 days! Very quick. The water in the jar will evaporate slowly so add small amounts of water as needed.

Ich habe schon bei verschiedenen Hersteller bzw. Lieferanten Moina-Eier gekauft. Nur mit diesen Moina-Eiern ist auch ein Schlupf geglückt. Kann ich also empfehlen!

The eggs hatched well around 70%, but the reproduction rate is around 30-40%. I tried feeding yeast and algae water. Better result was with algae water.
