Very nicely composed/arranged Iwagumi - the flashiness of the bettas, however, kind of distracts from it (plus, they'd probably get along best in a jungle planting, where they can hide from each other, and establish territory) ... do you know/can you tell us the species of moss you used here?
I agree. The bettas are in there temporarily while I set up another tank for them.
The moss is simply a marimo moss ball cut into flat sheets. It gives the look of a grassy field against the "mountains".
