Setting up a 125. 72 X 19 X 22. I'm planning on 5 Balas, 3 Tinfoil Barbs, a pleco or 2, Some snails and I was thinking 4 Bichir (upper jaw only). I'll be running a eshopps WD-300CS and a pump. 1600 GPM. And a sponge or 3. Heater or 2. Pool Sand Substrate, I'm planning on planting the aquarium, Hiding spots, and the like. My question is this...Too many fish?
