Which tank size should I buy (poll)

[MonsterFishCreeper]

Next week I'm going to buy either two 55 gallons or two 40 breeders. These tanks are specifically for a group of Cryptoheros nanoluteus and Cryptoheros panamensis. I have 6 of each species and would like to keep all 6 of each group if possible. The species likely will never mix, these are species tanks. They are probably going to be life long tanks for these groups. If things get crowded or violent in either tank I'll rehome fish as necessary. The main point here is I want to keep these groups in tact if at all possible.

My options are double stacked 40 breeders or double stacked 55's. Please don't say just get 75's or something, these are the only two tank sizes I will be able to get right now. Also, I know that either is enough space for at least a a pair or a few of these fish long term if not the whole groups, especially for the 6 nanoluteus which stay smaller and would probably be fine as a group of 6 in either tank size.

I would go with 40 breeders. I like the width and would probably give you more options with scaping the tanks

Double stacked 55's, NO DOUBT (AND I LOVE 40b's/ I have 3)....

Whats funny is aquavisor says the 55 is 107% stocked with the nanos but the 40b isn't 100%. I think that thing is just based on overall sq inches though. I just don't know if I feel that smaller fish like this will appreciate more spread out territories with a 55. Neither species is likely to get over 5"

I like the 40 breeders for the bigger footprint. But since they only max out at 6" the 55 would be better because it will provide more water which equals more stability in the sense of water quality. FYI a standard 55 gallon is approx 55.93 while the 40 breeder is approx 44.86 gallons. My calculations not be 100% but the idea is that the 40 breeder is bigger than it sounds while the 55 is pretty much spot on.
