Ah HA! My two assassin snails are laying eggs now! They are quite different than the pond snail eggs I posted earlier. I've found 6 eggs total
There are 3 here (2 in the lower 1/3 of the pic and 1 in the upper 1/3 of the pic):
And there are 3 here (all 3 right in the middle in a line from left to right, with the middle one just above the blurry shrimp tail)
I'll be leaving these alone.
