I know you guys get asked this question alot and I have been searching but can't really find any info for what I need. I live close to custom aquarium manufacturers at extremely reasonable prices, I can get up to a 72" aquarium and probably 2.5-3' of width on it. I am planning a new tank that size to hopefully aim for within the next 6 months while I work to get the extra cash as I grow out some ocells in a 90g. How long do you think I could keep a few ocells in an aquarium with that type of footprint and what would a good height be?
