Been going back and forth over this for quite a while now and am really contemplating discus. I feel like now that I have some funds I would like to dive into discus. I have a 75-gallon tank with a Rio Nanay Scalare and a Green Severum. I know the severum probably wont work out here but say I were to keep 4-5 discus in the tank with just my angel (almost fully grown). I have a sunsun canister on the tank. Currently change 50-75% a week but can up that to 2 maybe 3 times. I can buy the discus as 4inchers from Monster Aquarium inc here. I think they are pretty reputable, I got my angelfish from them. Anyone advise otherwise? I probably won't add any other tankmates with them for a while until I get comfortable with the discus. Also hoping to add a universal rocks background, "Deep Water" and my substrate is sand. I know BB would be better but I'm not sure I can do BB.
