Honestly, I'm not sure if I'd want that. Maybe a 29 gallon sorority with a BN Pleco and a big 75 gallon Biotope centered around a Black Ghost Knife, but that's about it.
Sounds good :D is the 37 gallon on the stand? If it is, I'd use that for the Dojos. You could get more White Clouds, too! Your so lucky, I have a tank limit of 3. Id love a 75 gallon for a Black Ghost KnifeFish, but noooooo.....
