Well I have maid up my mind and my planted tank is going to be my 100gallon-show tank. At this time it has 12 full size angels in it. Their bodies alone are 3 ½ to 4 inches across. From the bottom fin to the top fin they are 10inches. I plan on fully outfitting the tank as a plant tank with a pressurized co2 system. Will my angels be ok in the tank with the co2? If so what is the maximum co2 level if I have them in with the plants?
