i think you will be fine excluding the pleco, why not swap in out for a smaller species? bgk i doubt will hit its claimed max size of 1.6 foot anyway... have a search on here for big bgk's...
And they wont push me over my bioload?
So the stocking will be:
1 Green Severum
1 geophagus red head (not tapajos but they're red heads)
1 Blue Acara or Firemouth (undecided)
6 Giant Danios
1 Striped Raphael Catfish
1 Four Line Pimelodus
1 Sailfin Pleco (for 2 years)
1 BGK (unless it outgrows)
Just need some others to approve of this stocking as well to ensure that its good.
Tank params:
Temp: 76F
ph: 7.6
wc schedule: weekly 30-40%
perhaps a black knife ghost fish, get to about 12 inches and just dang cool to watch.
