Crazy? No. Just ambitious. And I respect that! But it's also ill advised IMO.
If you can keep discus and if you can grow out a nice planted tank, a planted tank with discus is not such a big leap IMO.
But the reality is most people's first planted tank (or two, or three) aren't so easy to keep. You make a lot of silly mistakes, and all sorts of drastic measures wound up being taken to save/fix your aquascape. That's all fine and well for a lot of fish, but I wouldn't put discus through all that.
I think you should absolutely keep your aspirations to have a planted discus tank. But personally I think it's a really, really bad idea to do it until you have had at least one successful planted tank first.
PS - I'm sorry to rain on your parade. But I do have your best interest (and happiness) in mind.
I thank you for your response and I respect your opinion.
I really doubt I will have more than one tank in my house which would be freshwater. If (when) I add a second tank, it will most likely be a 65G cube reef tank. When I was a kid, my bedroom looked like a LFS, but nowadays I just want one or maybe two tanks in the whole house (with the exception of a 10 gallon quarantine tank).
Being around the reef hobby, I know not to add live corals to a tank for at least 6 months after setting it up. It takes at least that long for the tank to become stable. I was going to take a similar approach with Discus.
I plan on setting up the tank with the plants listed in the Booth article, a school of tetras, a few SAEs, and a school of small corys. After all is well, I'd start raising the temperature over the next month until I get it into the 82F range and then let the tank stabilize for another month.
The discus probably wouldn't get added until the tank is established. From what I've been reading here, most people feel that is around the three month mark on planted tanks once the "new tank algae battles" have been beaten.
In my previous experience with Discus, they were extremely hardy. I did start with fish from Wattley's warehouse in Miami, and I did 50% weekly water changes. They grew like weeds and I never had a single problem. I did keep them in a single species tank, so that may be why they did so well. This time I'm planning on a community tank, so there is a much greater chance of introducing disease and possible stress.
I am ambitious and a little bit crazy, so I am going for the planted discus tank on the first try. If you think I need to wait longer than 3 months before adding discus, please let me know what you feel is adequate time for a planted tank to become established.
