I know that Jilly has had discus, but she is quite busy lately and doesn't come on quite as often as she used to.
You could do a search for various discus sites..that's what I would do..in fact, here's one to start with..you can email these folks and ask them anything about discus and they could certainly give you an educated answer....
Discus Madness I would go to a discus specific site to get that kind of info scarlet. They are a pretty particular fish to try and keep and the best info you'll get is from folks who specialize in them.
Wish you all the best..I would love to keep discus myself, but I don't think I can do a tank as large as what I would need for them...right now anyway..lol..If I had just ONE large tank I might consider it, but with all these tanks I have all over the place to care for, one more large one would put me over the top I think..lol.
