I'm planning to setup 80 us.gal. (300Ltr.) tank soon. I'm wondering what to "put into this tank. It's quite a lot of place in comparison to my actual 19 gal. tanks. I have three ideas about settings to this tank. So:
1. Sand-dwellers from Tanganyika, the most interesting species for me is Xenotilapia spiloptera.
2. Geophagus, some of them are quite good for such small tank, but I don;t think about the most popular like Red Head Tapajos, I'd like to get G. dicrozoster or G. winemilleri with tetras or something like that.
3. Central America, I mean one or two species, Cryptoheros/Thorichthys, one pair of each with some tetras.
I'd love to see what do you think about these ideas. Which one would be the most suitable for 300L tank.
