If they are stressed at all they won't lay eggs... But if they did, I think you would notice. They lay them in the morning and carry them around for at least five or hours. Those carrying eggs are pretty protective of them and will keep their distance from other fish.
Mine laid eggs again, but she seems to not know how to stick them to things properly and keeps letting them fall off to the substrate where I can't find and retrieve them.
She is the largest of the females but still pretty small, so I am guessing she is still a juvenile getting used to spawning.
Another thing - they can be picky about water and food for spawning. It is really easy for me to keep them as my water is in their normal range. I also use special medaka water conditioner, medaka vitamin and mineral supplement, keep them in a tank designed for medaka, and have special medaka soil and gravel in the bottom... Oh, and also feed them special medaka formula. So they are are very spoilt.
Have you got any photos of what kind of habitat your medaka come from Tamyu? I love setting up biotope style tanks but sometimes it can be difficult to find good resources online.
Hmm, I don't have any in water pictures... I plan to head back this weekend to see if I can catch a pair of tiny goby. Last time I only found one, but they are social so I put it back. Once I put one in my aquarium, I would be stuck with it... And if I never found another it would live a very lonely life. So this time I will cross my fingers that I can catch two or three.
I will try to take some photos of the location and see if I can get some that show into the water well.
