That's what I did when I was last active in the hobby. I had dbl stacked 60s plus 1 or 2 40 gallon JEBOs on each wall.
In total I had about.. 12 to 14 tanks... the jebos were for larger adults and the 60s were divided 3 ways and housed my ILC imports... back then I'd say I spent about 10k on my "fishroom".
Lol I'm just getting started.
