Hi! As I've said already in other polls I'm planning on upgrading my 30G tank to a 38G tank (which is 36"L x12"W x 20"H). Discus have always been my dream and I was wondering, now that I will be moving all the fish from one place to another, if I could, after moving the fish currently in this tank to another tank, have 3 discus in this tank with a few more fish (like a school of 8 cardinals or rummy nose), and with artificial plants. Please I would appreciate any answers, recommendations, pros, cons, anything so I can make up my mind and be very well oriented. I know I can always count on you guys. Thanks!
