So this weekend, the remaining two eggs hatched. The third baby is by far the largest of the bunch, at almost twice the size of the others. It was born with no yolk sac left at all. Baby #4 was born like the others. About the same size, and with the yolk. I had to order more mysids already. I still haven’t seen them eating, but all the food I give them disappears eventually. And they seem to be pretty voracious once I’m not looking.
