A medaka lives about 2-3 years, which is why they reproduce a lot.

They do not require particular nutrition, in a balanced tank they find the food necessary for survival, but if desired it is possible to feed them only with finely chopped goldfish food.

Be careful that by giving them food they could become lazy and not prey on any mosquito larvae present in the tank.
