If you don't know anything about discus, you have a lot of work ahead of you to get informed.
First, discus like to be in a group of 6 or more so if you are thinking of getting "just one or two" you might as well stop right there and forget keeping discus at all. A 46 gallon bowfront isn't an ideal discus tank at all. You'd be able to fit 5 adults max in there and you'll need to keep up on the water changes.
Discus do not require soft/acidic water unless you are tyring to breed them, in which case the 46 wouldn't be an ideal breeder tank. Only wilds will require soft and acidic water to be healthy though having soft and acidic water in a tank housing commercially bred fish won't be bad.
The BEST way to get discus is to buy 3"+ specimens as they are not nearly as needy. It's best to buy 8 juvies like this and grow them out in a 55 gallon bare-bottom tank doing all of the necessary water changes. It's best to buy fish that are from the same spawn and grow them out as well rather than picking 2 from this tank and 2 from that tank and mixing them. You could also buy 4.5-5"+ fish from the same source and put them into your tank. It's really best to QT them before adding them to the same tank but if you get them from the same source they will be okay in the same QT tank.
If you want nice quality discus you might conside
Houston Aquarium Warehouse - Gulf Coast Discus - Gulf Coast Aquarium Dan is only a few hours from you at most and he'd definitely be worth the trip. Check out
www.simplydiscus.com and check out the "Sponsors Section". Look at Kenny's Discus, and Central Ohio Discus. Also check out
UtahDiscus.com for some great stuff. Any four of those retailers I recommended would be EXCELLENT choices. These guys are TRUE professionals and their quality is superb. You can't go wrong with either one of them. Very nice people and always willing to help you out with any questions that you have, especially Kenny at Kenny's Discus. Check to see what he has available in his "July Shipment" thread. I'm sure he's sold out but you can get an idea of prices for each size and see some strains that are available.
