It's not easy for me to get pics of the babies but the jars are doing well. Jars do get direct sunlight for maybe 6hrs a day. Temps aren't too hot inside the house. On hot days when the house is warm I move the jars out of the sunlight. Babies have been going strong for the last 3 months or so of the year.
It's hard to say. Maybe 3-4 so far this summer in the quart jar. There should be quite a few in there by now. Wish I could take it apart & count.
The half gallon has not had free swimming babies yet. I saw a berried female a couple months back but she must have dropped her eggs. I see dark saddles. I check the jars every other day for a quick look.
