A couple of weeks ago, I took my son to the Grow Haus for home school co-op and picked up a dozen tilapia. So in addition to those fingerlings, my AP fish tank now contains a couple of large fancy goldfish, two smaller goldies, and three large (~10") catfish of different varieties. In the sump I have some daphnia and ghost shrimp I'm hoping to breed for fish feeding. I have duckweed going in a couple of tanks. I do have some commercial feed, but the fish seem to like table scrap rice and meal worms best.

The tilapia are two varieties, Red and Blue. Supposedly there is a third breed particular to my area, called Colorado White. All mine are males, raised at one of the state penitentiaries. Supposedly there is guy in the area that raises catfish, which I'd like to mix into my tank.

I'm still refining bell siphons and have two (10gal) modules cycling reliably, with two more in troubleshoot mode to get them to start and stop better over a range of inflow rates.
