At what age could your medaka start to take down / eat a baby brine?
Mine appeared a couple days ago... but seem to small yet. ...significantly smaller than a newborn guppy.
Anyone with experience feel free to respond.
Regarding selling them... it seems that fat healthy ones start producing eggs at about .75 inches. (My blue eyed pearl medaka did).
I sure it will be up to your buyer. Once you can sex them, I would think most would be game. ...Depending on their stock levels.
Some of the thin yellow/golds that I picked up at over an inch but thin... and I haven’t seen eggs on them yet.
if you are shipping them... at about a half inch then seem to travel ok.
