The first spawn (now 10 days old) are around 1/4" long and are starting to pick up some color. Krista has remarked that they seem to grow a new body part every day. The current count is about 20.
The new hatchlings are doing fine at around 3-4 days old, and are scarcely half that size. I counted about 35 on the second day, but they've gone into their "hiding" phase where they spend most of their time buried in the filter/debris on the bottom of the tank. They aren't moving around much, but neither did the first batch at this stage.
If all these guys survive, I'm going to have a lot of fish to deal with.
