5 babies, at least!
As of this morning I found 1 baby still in one of the breeder nets and 4 that I could see at once in the brooding box. Originally there were 2 in each net- one I found dead and the one is still alive. Because I see the one regularly, I'm guessing that if the other 2 were alive, I'd see them once in a while. This means I think there is a vacancy in the one net so I'm thinking of moving one of the "boxed" babes out.
Here are some photos of some of the sibs and the brooding box. It's hard to make out what is in the box and what's on the outside- sorry about the quality. Remember, I'm taking picts of things in a box behind a bow front! The first photo here shows the whole box. There is one baby on the left by the hermit and snail shell, and another in the right corner. You can just barely see one little dude in the right corner, half way up. The next photo is a close up of the same baby, it seems to be out the most. The 3rd shot shows a small white blob on the floor next to the shells. That is a live baby, it turned dark and moved away after the shot.
A quick note about lighting... I took the regular daylights off of the tank once I put babies in the nets. There is red lighting all night long, and ambient light through a close window with a strong southern exposure during the day. On a bright day, the babies are hiding by 8:30 am. Today it is dark and cloudy and with no lights on in the room the most social baby is out in the corner, the others hiding farther out than on a brighter day.
