Hello! I'm also new and am wanting to buy discus too! I have kept 4 before so I can give you a tiny bit of info on discus. For a price, it really depends on how much YOU want to pay. I can go to one place and buy a 2-3 inch for $18 or I can go to another place and buy 5-6inch for $399. I recommend that you buy 4-5 inch discus for about $69 each. How big is your tank and how many discus do you want to buy?
