So its my birthday tomorrow! and with my birthday money and the money ive saved up I am getting a bearded dragon and in my 75 I want to get some discus. Any pointers on keeping them? How many can I keep in a 75 gallon tank? Hard water? soft water? temps? What kinds would look best? I saw these red dragon ones and thought they were awesome. I have black sand a huge piece of fake wood and am thinking of getting some really bright plants to make there colors pop, and I plan on feeding a color enhancing tetra flakes with floating pellets for food.
