Fish in a bucket

Fish in a bucket

Observation - Fish in a bucket - Global. Description: We saw this and several others swimming around a marina in France, when we asked the French though we couldn't translate it to anything that we had heard of before! The head is on the left and it swam by rippling its wings(?) from the front to the back.
