been thinking about filling my last built in tank, another 30 long... usually there is a big push to getting lots of big beautiful fish into the tank... this one, I'm thinking of starting small with micro-fauna, and plants 1st, with the 1st really visible inhabitants being an overflow from one of the colored neo shrimp tanks... I'm not even sure what I want to pursue for fish yet... I asked about native Killifish the other day, and there were lots, however almost none that are commercially available, but that's the direction I'm leaning right now, for this tank... thinking no heater, so a room temperature tank
