The platy fry are doing really well. I lost one about a week in, but that leaves 18(?) alive at my last count. I'm hatching brine shrimp in a room that's warmer than the rest of the house, so I can produce a new batch every 24 hours for them.
I also picked up a 20L at a Petco $1/gallon sale that I'm going to make into a planted, rimless shrimp tank with a custom stand. Since it's for shrimp, I'm going to try a "Matten" filter in one of the back corners.
