beautiful setup! the leaf litter adds a very nice touch, what type of leaves are those? Did you cure the manzanita in anyway? A friend of mine tried using it and lost all his ropefish.
Nice! Are you going to keep anything else in there or just bichirs?
If you wanted I think congo tetras could work quite well too, and would add a lot of movement.
congo tetras are pretty sweet, but I would think they would get eaten eventually wouldn't they?
