I would go for a smaller species of geo like Red heads or pindare. Imo 80g is too small for surinamensis type. Btw most surinamensis are mislabeled and are actually G. abalios or altifrons
I have a 240G... this will be a temporary home for them... sorta like a grow out i guess... eye candy for my bedroom since they are active and fast paced.
Just wanted to see how long I can house them in their for...
