Cool tank! I absolutely love bichirs, my buddy has two senegals and they are sweet, cool personalities. Nice driftwood, will look awesome when covered. Really like the contrast with the dark gravel too. Wisteria looks like a cool plant too, might have too look into it- I assume it is pretty hardy based on the low-tech setup?
I may try to catch your fish if they are big enough
