That is good sized tank for fish only and the depth will not be an issue like with corals.
I have deep blue brand frag tanks also that are 4x2 x 12" and 16" [60 and 80 g] but they are semi newly introduced..
2 foot wide tanks are great for hardscaping..You can create nice rock work with pen space still.
I actually measured it after that and it's like 18 inches wide! So I was off a lot but hopefully it's still good!
