I don't bother spending the time breeding any live food such as mosquito larvae, daphnia, brine shrimp etc. I figure that medaka outdoors get enough of a varied diet from small insects etc that land on the tubs' water surface. Incidentally, I find that once medaka fry get to about 3 weeks old it seems they are big enough to eat mosquito eggs on the water surface. With fry less than 3 weeks old the mosquito larvae hatch out ..... fry older than 3 weeks then no signs of larvae. I've kept fish outdoors for many years. I very quickly experienced the problems of herons and dragonfly larvae eating the fish. Since then I've found that both the heron and dragonfly the problems are solved if ponds and tubs are covered with 10mm mesh netting. See my videos on my pond and the DIY video showing my netting covers for my tubs. I've often observed dragonflies hover about 1m above the pond; apparently see the netting, which I keep at least 50mm above the water surface, and immediately fly away somewhere else. It's a long time since I had a dragonfly problem.

Yes, exactly that, I sort through the plants to find the short-root sections ..... however once I've got some I find at warm temperatures they can reproduce similar size plants very rapidly. Also the goldfish in my pond love to eat the roots of the larger plants but they never manage to keep up with the reproduction rate of the small plants so I have a large reservoir of small plants available if I need more. My spawning mops may get a small amount of algae on them sometimes but I've never found them to get yucky so I never clean them. When I finish collecting eggs I rise the mops in tap water and leave them in the sun for a few days to dry.

Asia ..... with a sub-tropical climate.

@@km-qh3rs makes sense, I was hoping you were in the U.K. so I could buy some eggs 😁

Hi. thanks for commenting. I'm honestly OK with receiving any feedback. However I have no ambitions to be seen as an "influencer" or renowned expert on medaka. If you listen to the intro to my first video on Jan 6 you will note that I'm a really old guy who decided to find out how difficult it is to start a youtube channel. Talking about my medaka was the first thing that came to mind and I didn't expect to produce more than 1 or 2 videos before deleting my experimental channel. Yet here I am 23 videos later .......... I fully appreciate your point of view but regret that you'll have to look somewhere else if you want slick, concise, high impact videos. I sit down with my battered, old, no brand name Chinese smartphone and ramble on talking for about 15 minutes ..... another 10 minutes minor editing and uploading to my channel. For me to make a slick, high impact video would probably take me 2 to 3 hours scripting it, re-shooting various clips, dealing with sound issues, major editing, etc, etc and I don't have any interest in that sort of stuff. My type of channel is an amateurish, personal video log, vlog, about my medaka on an approx weekly basis and I think I said in my first video that probably 99.9% of people would find it boring. So I now continue it as my own personal vlog and I'm happy if there's anyone else who finds it interesting enough to watch. I fully accept that it will appeal to a very limited audience. The analytics show that an average of about 300 people start to view each video. About 50% or 150 viewers very quickly switch off within the first 30 seconds. There is then a slow decline in the number of viewers as the video progresses but there are still about 25% or 75 viewers who watch the whole video. I'm happy with that.
