I saw at least one baby cherry red shrimp in the plant tank yesterday. It was pretty cool - about 3 mm long. It isn't ideal breeding habitat for them though - between the filter and the pygmy corys, I don't think the survival probabilities are too high. The tank is good overall - it's densely enough planted by now there would be adequate hiding spaced from anything but pygmy corys.
I'll see what the survival rates are like. Hopefully I have at least one male among the shrimp, and they'll breed again soon. It takes about 28 days, apparently, after the eggs are laid. We'll see what happens next.
