advantages/disadvantages?

[J.R.L.]

i have the opportunity to buy a nice 65g tanks that 48Lx12Wx23T what would be the pros and cons for a tank of those dimensions?

[capn_hylinur]

Pros------the long tank will give more swimming areas for fish that like that stretch to get up speed.

cons----it is still on the small side to keep tangs--which are the kind of fish that need the long stretch for swimming.

Con.....a 12" with won't afford proper circulation.

You rock would also have to rest on the back wall.

Pros
48" length gives you lots of lighting options (it can be tough to light a 30-36" tank), and at only 12" wide, any light you choose should brighten the tank from front to back no problem.

48" x 23" is a nicely proportioned viewing window

65g is a good size - lots of options when it comes to fish

At only 12" wide, the rockwork won't be very deep, so you'll likely see more of your fish (I have small fish that seem to be able to spend minutes cruising around inside the rock before they come out again, because it's 14"-16" wide in places and runs the entire 48" length of my tank.

Cons
12" width can be challenging to aquascape - not impossible, you just need to be creative

The front-to-back dimension can also be a hindrance when it comes to corals - most tend to grow in all directions, and 12" isn't much room for, say, a large LPS coral or an anemone to expand.

If you install an overflow, in-tank skimmer, large powerheads or other equipment, it can feel as though you're losing much more usable space than if the tank was 18"+ wide.

Your stand (if it's a factory stand) will probably only be about 10" wide inside, so it will be tough to fit a sump or equipment - you might need a custom stand, or you could set up a refugium beside the display rather than underneath.

That is going to be very tough to aquascape correctly. By correctly I mean allowing for proper flow through the entire tank and rock structure.

one of the options would be less live rock in the tank and more in the sump plus a deep sand bed refugium.

Next time I wont go with an 18" tank,it would have to be at lest 24"

I would stay wth dimensions that width and hight are the same or width larger.Length/width for fish swimming room and surface exchange area

I would go with 24 inch height and a minimum of 24 inch depth (front to back). Width is a function of how much you can afford.
