First fish that comes to mind is a blacknose dace... But the picture quality of the first one isn't the best. Definitely interested in more pictures of a full fish if possible. If it is what I think it is and it is a blacknose dace, they can adapt to pond life but will not reproduce without a source of running water to spawn.
