265 gallon for a 14" male not big enough.....
This just furthers my opinion that people on this forum get a bit out of control with their recommendations on tank sizes.
I'm sure your fish appreciates a larger tank, but it's by no means a necessity.
And I agree with the poster on page 2 I believe. It all comes down to water quality. If you have a small tank for a Dovii (180 or 240, etc...), you're going to have to do a lot of water changes. But as long as the water quality is kept up, I don't think a 180 is too small.
