Hello,
i have forgotten something ... my bichirs are very active, day and night!
Such a plant tank isn't a over-night project. I had bought only 4 little plants, the tank looked very plain to this time - after 5 months i got this appearance. The bichirs had produced many nutriments, so the plants could grow this way (now i have too much of them, a nice present for other fish-keepers).
It was interesting for me to see also the activities of the bichirs grow with the plants ... i will not miss them (both bichirs and plants).
Greetings
Uwe
