Our population control program for the guppies continues. This past weekend we moved three fish from the female tank to the male tank. A month ago, we could have sworn that these fry were female, but as they grew it became apparent that they were boys -- at least, if our current visual assessment is accurate. We've been wrong about this before.

We're told that guppies can change from one sex to another if necessary to reproduce in a given group. Maybe that's what happened with these fellas. In any event, we'll be chaperoning them for a while.
