Thanks, guys! As far as their disposition, they clearly run the tank. However, they largely stay near a rock in the left corner of the tank. On occasion, the male takes a cruise of the tank. The female RARELY leaves very far from that spot. Mostly, they just chase other fish from their corner, and otherwise leave everyone alone. So far, the most low key parachromis I've ever kept, and my favorite pair of fish to watch ever. They haven't spawned yet though... so we'll see what happens if/when they do that. For now, they just hang out together constantly.
