Welcome to the group! They might be a pretty penny, but they're worth it!

I've seen a bunch of people in Japan and Europe with tons of ponds and no air running. Without running air do you notice your medaka being more or less active? Mine always seem to love little to no flow.

Keith is the best!!

@madcorgi aloha! Welcome to the group! Feel free to ask questions and share your experiences on here!

@leilanblue maybe closer to 10 liters, congrats on getting some rice fish!

The same thing happens to me usually when I check for eggs I check both the sponge and the spawning floats. In a paper I read about breeding these fish and they only used the sponge filter as a spawning medium haha. I'll bet the java moss will work fine, can't wait to hear your findings!

That's awesome man! Love all the little ponds you have set up, tons of babies too!

That's very cool! Glad to hear you found some cool strains and that your orange medaka are doing well also!

Very cool video, thanks for posting it! Looks like they're all happy and doing fine!

I use these small sponge filters and I turn the air flow down to where its very very low, I was able to raise them without a sponge filter but I experienced a lot less losses when using a small sponge filter. https://www.amazon.com/Aquapapa-Sponge-Filter-Betta-Aquarium/dp/B01L8PXSNQ/ref=sr_1_4?crid=3PKP0KLUG2BC9&keywords=single+small+sponge+filter&qid=1654355607&sprefix=single+small+%2Caps%2C61&sr=8-4

I've always wanted to try to culture walter worms(similar to white worms) for this but I've been too lazy to get a culture started lol.

Here's links for some of the stuff I use for fry rearing.

I've only raised them indoors in aquariums but I've had great success in small aquariums, and I've had the most success in small containers with a single sponge filter on a very very low air flow. I feel the containers work the best because of the small area that you can concentrate food and make sure everyone is eating good. I will say that you have to be on top of your water changes using the smaller containers as the can foul up with uneaten food pretty quickly, I use a turkey baster to suck up uneaten food and water for the water change. Personally I've never used plants for my fry containers but I don't think it would hurt at all, although mosses might make it a little more challenging to suck up uneaten food as it would get caught up in the moss. For feeding I like to use serra micron for the first few days, then after day 3 I add a tiny amount of baby brine and watch to see if the babies can actually eat them and if they do I start adding them along with the serra micron. If they aren't able to eat them yet I just retry that process daily until they are able to eat them. Once on baby brine they will start growing very quickly(but make sure to keep feeding the powdered food also), and eventually they can start eating small pellet foods such as the Hikari gold bag from Japan. Personally I don't add them back with my adults until they are eating pellets but you might be able to add them sooner if you really needed to. For feeding regiment I like to do serra micron and a small amount of baby brine before I leave for work in the morning, and then serra micron and a larger amount of baby brine when I get home from work. On the weekends I try to do 3 feedings but that doesn't always happen haha. For how much to feed I would recommend adding food and then watching your fry eat for about 5 minutes and start basing how much you feed off of how much they can actively eat in that amount of time. I know it might seem like a generic answer but it really works if you take the time to do it, it's fun to watch, and you'll learn a lot but just sitting and watching your fish sometimes. Also add a heater if you can, even the small preset ones work well, a little heat goes long way for growth but I would recommend 78 degrees as I seem to get the fastest growth at that temp with this feeding schedule.

@Suncoast Medaka thanks for the link!

Also love how it even has an area for the clip on light haha!

@Suncoast Medaka thats really cool! I always like being able to use other technologies to help with aquariums! 🤘

Legit the best brine shrimp hatchery in the aquatic hobby. I own 3 but use 2 haha. Where did you find the 3d printed hanger? Looks really solid.

That's awesome that your spouse is supportive of your hobby! I know what you mean with renovations my rack is about half done now and we are starting a complete remodel on our kitchen, so medaka had to take a back seat for a short while. What do you plan to breed in the fishroom, more medaka or other species of fish?

@CowMoo hey there! Welcome to the group! It looks like there's a lot of medaka keepers in the bay area and the west coast in general. If you can't find medaka locally I can help you find them online.

Man so jealous! Wish I could have been there too! It looks like it was a great time!! First of many meet ups in the bay I'm sure!
