I do not know what the dimensions are for the 60 gallon tank you mention. I would recommend a 48 inch long tank, not a 36 inch long tank. There are many mare options at bettr prices for lighting a 4 foot tank versus a 36 inch tank. Plus a longer tank would be shallower allowing fot chaeper T-5 lighting rather than the more expensive halides used on tanks deeper than around 18 to 20 inches. I would recommend either a 55 gallon or a 75 gallon, but not the 36 inch long 65 gallon tank. The 75 gallon tank has 1/3 more surface area allowing for heavier fish numbers with increased safety and allow for aquascaping that does not require live rock close to or leaning on the back glass wall, yet it is virtually the same height as the 55 gallon tank, so the 75 gallon really requires no more intense lighting than the 55 gallon tank so T-5 lighting would still be a good option. The T-5 lighting would be cheaper in a shallow tank such as the 55 or 75 gallon tank, than would most halide lighting.
