I was planning on a 36" 30 gallon tank initially, utilizing fish I already Benitochromis nigrodorsalis, a CARES, bi-parental mouthbrooding cichlid from Cameroon.
The day of the event, I ended up using a 36" 45 gallon setup in lieu of the 30 gallon. The added height came in handy for the very large plants and larger tetras and Westies.
