Which Breeder Tank To Use? Pros/cons?

I have space for a breeder tank (36" x 18"). I need help determining which size in height. 16" (40gal breeder) or 19" (50gal breeder) or 24" (65 gal breeder).

I know that having more gallons provides more options for fish and possibly less hassle with managing nitrogen cycle with proper stocking. However, since the floor surface area is a common denominator (38"x 18"), is there really a major difference?

FYI, I have maintained a 10gal for one year...( 1 dwarf gourami, 4 albino corys)(I kno six cories is better and the dwarf gourami may enjoy a bigger tank) in the process, I have learned a lot, and am desiring to take the next step for a bigger tank.

 

It really depends what you're looking to keep. Discus and angels would much appreciate that added height, but most fish stay in one level of the water column. That said, the bigger the better. Get the 65.

 

I have both a 40B and a 50B. I love them both for their footprint! I've wanted to add the tallest version to my ranks but the truth is that it would be extremely difficult for me to reach to the bottom to get anything done!

FWIW the 50 is a perfect height for angels. I'm not entirely convinced that the 40 has enough height for them to be really comfortable.

 

I agree bigger is always bettet.

Indeed, I am thinking about 1 or 2 types of schooling fish (quantity is dependent on size of tank, 10-12 being minimum, though). But after reading several Fishlore posts, I am considering the idea of a poster-child-fish
