They're out and about and swimming now. I took their dad out because he had developed the strange habit of flaring at me when I was feeding his fry, but not offering him any food. I think he was jealous.
I counted as many as four up at the top at the same time. I'm hoping that isn't all there is.
They're a week since hatching now (Tuesday), though. They look pretty good...what little I can see of them. They're so cute and little.
