medaka rice fish outdoors - size of fry to be safe with adults

A rough analysis of what size fry should be in order to avoid being eaten by adult medaka.

The little pieces of sticks were very helpful. What a great idea 💡 👏 👌

Thanks. I still have a few more weeks of vacation but will try to post a new video soon.

Beautiful collection and very lively Medakas 👍

Thanks

Cool idea, thanks for that. My only concern would be that I would not like babies to be chewed and damaged by that... I mean, their tails are not 2mm thick. So I put my medaka juveniles together with adults only when reaching like 2 cm and more. Also, I don't want them to be pushed away and outcompeted when feeding.

Good points Jan, I don’t have any fish yet so need all this valuable information ✌️

@@gayefanner731 well I am not an expert, even tho I've raised quite a few species of fish. Usually the same principles apply. And I always take the better safe then sorry route :) Best luck to you :) Ye, and keep the videos coming, you have good ideas and I like to watch them.

[@km-qh3rs]

I understand your point of view. On the other hand, I've never observed that adult medaka are fin nippers and never seen them try to eat 1cm long juveniles. Also I drop food at different areas in the tubs and pond so that all fish have a chance of eating.

your adult medaka are whizzing about much more than mine…

[@km-qh3rs]

They were hungry at the time of filming. However, if water quality is good and the medaka are healthy, their activity rate depends on water temperature. At present, water temperature in my tubs is about 28degC so the fish are very active. At, say, 18degC they are less active.

I have a 1000-gallon Koi pond in my backyard...I want to add some Medaka. There is considerable vegetation in the pond. Since Medaka are known to be prolific breeders, do you think the fry can survive in hiding places?

[@km-qh3rs]

I've heard that koi are not much good at keeping mosquito larvae under control. If this is correct, then medaka should be reasonably safe from predation by koi. Maybe another way of looking at it ......... do the koi breed in your pond? If so, then medaka fry should have a similar chance of survival as koi fry.
