Agree. Only get a female when it is densely planted.Moved a portion of duckweed and other small floating plant, and put a bamboo there. And put the other plants on weighed tie ins for now. Still work to do, but he seems to like the changing setup.
As for another fish, we'll see. If his temperament allows, I'd like to pair him with a girl gourami, but I need to finish setting this tank up with more plants (or wait for these to grow) and put driftwood before I attempt that.
