I would avoid the 65. The main issue is the height to width ratio. With it being 24" tall and 18" wide, it makes aquascaping more challenging. You will end up with either a scape that looks too short for the tank, or just a big pile of rock staked up against the back wall in order to get it tall enough to look ok. Also makes it a little harder to light if you want SPS.The dimensions part of this caught my eye because obviously I need to finalize them before building a stand.
I'm looking at getting started soon and a nearby LFS kinda convinced me to order a sale priced 65g reef-ready. They said it should be in within a week...it's now been three...not sure exactly what's going on or if I should even bother following up because the dimensions give me pause and honestly it wasn't the most welcoming interaction in the place to begin with.
I'm concerned because 65 is a taller version of a 40B and from what I'm reading I can't tell how taller would be any better, aside from the added water volume. Also 65 is not a size I really see discussed...conversation seems to usually center on 40B, 55, 75, 90 and 120.
I know I do want to go with pre-drilled...just some fear of choosing the wrong size to start out in the hobby.
