I need your help settingup a new tank

[Omda1]

Hello all,
I am not new to fishkeeping, but new to African cichlids.

I am setting up a new tank, in which I am hoping to keep Aulonocaras Peacocks. I did alot of reading about them, and so I know all about overstocking, their mild Aggression, the need to overfilter, ........etc.
HOWEVER, my space is limited so I am having a bespoke tank built to order, and so I have 2 options available to me (for 2 different locations)

Option 1 is a 3.9 feet tank: (3.9' x 17.7" D x 15.7" H) which is (110cm L x 45xm D x 40cm H)
Option 2 is 2.0 feet tank: (2.0' x 21" D x 17.7" H) which is (60cm L x 53cm D x 45cm H)

Now here is my main question: Which of these 2 sized tanks you think I can use to keep Aulonocaras

Another question is: As you can see my depth on both tanks is on the lowish side 15.7" for the 3.9 foot tank and 17.7" on the 2 foot tank, is this an issue with Aulonocaras?

Thank you very much for any advise you can give.

Good Morning

As most scientist will say "it is not the size of the enclosure but the quality of the water" .

Enjoy
