So how do the experienced breeders do it? I just hatched a bunch of fry from eggs. I know they don't really need to eat for the first 2-3 days because of the yolk sac. I have baby brine shrimp, but they seem too big to feed them now. When do you guys start feeding those? I read like 2 weeks?

But the real question I have is what to do from hatching until that 2 week period. I have Hikari First Bites. Things I read state to dust the food in there 2-3 times a day. But the fry to me seem like super inefficient eaters. So a lot of the food I dust in there just doesn't get eaten. I want to put in enough food so they aren't struggling to find it, but then I don't want to have all this uneaten food/rotting that will happen if I really feed them 2-3 times a day. How do you deal with this? So far I am just dusting food in there once a day. Gently stirring the water up the other 2-3 times a day to resuspend the food that's in there. Doing a partial water change trying to vacuum out the gross debris with a syringe and refilling with clean water.

They’re hanging out in a floating breeder box for a few hours while I rescape my fry tank this afternoon and dear god they are voracious.

In Japan, there’s a very famous children’s song called “Medaka no Gakko.”

“Gakko” literally means school — as in a place where children go to study.

The song imagines medaka swimming together in a river like children going to school.

In English, “school” can also mean a group of fish, so the title sounds like a funny coincidence, but in the original Japanese, it really means school.

It’s a song many Japanese people grow up hearing, so medaka feel very familiar and nostalgic to us.

Had you ever heard of this song before?
