I won't make it blackwater. Turns out the danios and ghost cats are from more than one type of stream. Look up videos of MP10 on youtube. Amazing piece of equipment.
Saw this video, this thing is awesome!!! I like the different wave functions, a shame about the price though, but I guess you pay for awesomeness.
Oh yeah, are you going to put the tippy tops of rocks peaking above the water to create the waves crashing against rock effect?
