A few more updated shots. Added fish and some vals in the background. Still need to arrange the vals better, just kind of shoved them in there for now...
I need to find a way to get the current to now flow back towards the powerheads on the front an back sides of the tank. Any ideas? Also, the Praecox Rainbows seem to hang out on the top portion of the tank furthest away from the powerheads. Maybe the current is too strong for them?
I'm thinking about trying to aim the powerheads at the front and back of the tank kind of diagonally towards the right side. This might alleviate the back-current.
