I have tons of babies. I wouldn't be surprised if I had well over 200. One problem I'm having is the food molding too fast. It seems to be molding within a day so I'm having to replace it very often. I think this house just has higher levels of mold in general. I can actually see different groups of babies. One group is just a bit longer and bigger than the other group, so I think they've molted at least once. I haven't lost any more adults so far. Other than the food molding, these things are incredibly easy. There isn't a large accumulation of poo either. The babies seem to be taking care of that. I only see small amounts along the edges of the tub.
