I think water movement is always a good thing, it keeps junk from
settling down in one place and keeps the water moving and the plants
too, idk if it matter or not, but i always like to have good water movement.
I think you could easily keep about 8 fish in there, if they stay smaller than
2 inches. Dont those barbs grow about 3? And what kind of tetra's do you have?
The tank looks really nice, really unique. Do you plan to add some kind
of foreground plant?
