IMO, the amount of rock you want in your tank depends on how you want to aquascape your tank. The rock is definitely necessary for your biological filtration but that can be made up with your bio media in your chamber 1 and 2.

in my 15 gal tank which was setup to house a watchman and pink streak too I arranged rock like this:

base rock underneath, leaving 4ish inches of space around it, then three smaller pieces of rock leaned onto each-other to make a "cave" with a few entrances

additional thing: if you lean rocks together, glue them. and always make sure they are beneath the sand
