三寒四温 　A cycle of three cold days and four warm days

メダカと春：
ここのところ三寒四温、昨日からは雨模様ですが、昨年夏に我が家にいただいた小さなメダカ達、水温が徐々に上がり日も長くなり、水瓶の底から水面に顔を出すようになり、まいた餌をよく食べるようになってきました。
Japanese rice-fish in spring:
Though it has been rainy and in a cycle of three cold days and four warm days these days, the little killifish we got last summer now come up to the water surface from the bottom of the water vessel to eat the tossed food because the water temperature is getting higher a little by litter and the day time longer.
