I'm building out a tank that I hope to keep some larger tangs in one day and I want to setup the aquascape to have lots of swimming lanes for fish.
This sketch is roughly what I'm considering - the arrows are where I envision open lanes that go from near the substrate to the top of the water (approximately 22"). The structures will be made out of Carib Sea Life Rock and have lots of spots for fish to hide and coral to grow. The 3 large shapes will have varying heights but generally not go above 12" tall. I'll create some smaller rubble islands in the front and perhaps the right side as well but they will not be more than a few inches high so I don't think they will impede swimming to much.
Is 6" enough space between the rock structures assuming they generally narrow as they go up in height?
Will fish swim around the tank in these lanes or simply pace back and forth across the front of the tank?
