Help Me Decide

[Butch]

I'm looking to upgrade my 29g with a 15g sump FOWLR to either a 33 long or a 40 breeder and cant make up my mind. I need your expert opinions. BTW, I would be drilling the tank for a beananimal overflow and transferring the rest of my equipment over.

I like the short long lines of the 33 and would build a stand to match the height of my 20 long planted tank that would sit on the same wall. I have a 48" Coralife NO light that I can use to light the tank (If I changed it over to a reef, I would have to buy 2 LED lights due to the center brace and length as well as the light above not being powerful enough.

For the 40 breeder, I love the depth on it and the semi-short look. I would have to buy lights for it, which I would go with the Stark 60w LED or a Kessil setup. The benefit of this tank is that I can take my current aquascape and move it to the new setup.

What would you choose and why?
