@ MEDAKA RICE FISH OUTDOORS hi, I’m going to be received 15 eggs this week. Thank you for the info. So far. I have a question regarding water change - do you partially change the water of the eggs? If not - when do you start to change the water? Do you change the next day after hatching? If you do - how much do you change? Also, I have seen folk use a brush to flick the powdered feed to the fry, not sure whether this might give too much. What do you think? How soon do you feed after hatching? Thanks I’m on a learning curve 😊take care 💕

If you are getting lots of eggs from your medaka then no need to worry too much. Most of them will hatch without too much care. But with only 15 eggs I assume you want to try to get maximum success rate. Depends on what sort of system you will use but some suggested points to think about. 1. White mold on eggs kills the embryo. So keep a space between all the eggs. 2. Optimum temperature for hatching eggs is about 28degC. Hatch in about 1 week so less time for mold to develop. 3. Hatching at 20degC takes about 2 weeks so more chance for mold to develop over that longer period. 4. Eggs in a small container at 20degC maybe water change 20% to 100% every 1 or 2 days. Eggs in a large container at 28degC maybe 50% every 3 days or maybe no change. 5. Fry are very very delicate for first 2 weeks. Risk of being damaged by change in water conditions or temperature. So only minimal water changes during that period. 6. If fry hatch in small container then only transfer to larger container that has very similar water conditions as hatching container. Transfer by scoop and NOT by net. 7. For first 4 weeks I change water by drip acclimating method. I change 20% each time. 1st change at end of 1st week. 2nd change at end of 2nd week. After that, change every 2 to 3 days during weeks 3 and 4. And maybe continue at that rate for another 4 weeks if I'm really keen on getting good, strong, healthy juveniles for that type of medaka. 8. Some fry feed only 2 days after hatching. I've found some feed immediately. So I feed immediately after hatching. 9. I've heard of the brush feeding method. I feed using a small, long-handled spoon as shown in my video Fry Management - Food. I think it's easier to gauge quantity that way. 10. The above are only suggested points to think about for eggs that are important to you. You could probably ignore most of them and still get a good success rate. Good luck.

Another great video! How often do you feed your breeding fish? Can you share with us a bit about where you got your original groups of Medaka? How expensive are they in your area? They can be up to $15 Cdn per fish plus 13% tax in my area.

Thanks. I usually feed all the fish twice a day. But the important issue is how much food to give. It appears the advice sometimes given for aquarium fish is to give the amount that can be consumed in, perhaps, 2 minutes. I haven't actually timed it, but my guess is that I give the outdoor medaka the amount that they can eat in, at the most, 20 seconds. But also the amount I give depends on water temperatures. If it rains all day, maybe I don't feed them at all. I think that in very many areas outside of Japan, including my area, it's really hard, if not impossible, to find medaka for sale from commercial sources. Perhaps similar to my area; very, very occasionally it may be possible to find a private source on local social media but even then , prices for the cheaper (say, red/white) medaka are probably about US$7 and it's necessary to travel to pick up at the source. Very limited range of types available but prices of those with lame, long fins, etc may easily be double or treble the cheaper type. Also more expensive for a matched male/female pair.

I assumed you would have many options to buy medaka locally. We are made to believe here, that medaka are very common in your neck of the woods.

@@andreagalda28 Again I emphasize I'm not an expert ..... but I think that medaka are only easily available in Japan ..... and there they can be obtained from home improvement stores to specialist medaka shops to roadside stalls to online stores to local weekend medaka street markets etc etc etc. As far as I'm aware, almost everywhere else outside of Japan, including the rest of Asia, they are hardly known, usually difficult to obtain, usually limited varieties and usually expensive. I haven't been to a local fish shop for a long time but I expect they still don't have any available. I don't live in Singapore and I've never been to this Singapore shop, but as an example of prices you could look at madshrimp.com which lists online red/white medaka for sale at US$6 each.

Yeah, I also watch a lot of youtube videos at x1.5 speed. My wife often tells me she wishes she could listen at x1.5 speed when I'm talking to her.
