I checked out this book from the library and I'm not sure what to believe as it says you don't need a very big tank for Discus, even in a community. That seems just plain wrong!
Here is the book:
Here is the info on Discus: (written by a Cichlid expert, Mary Bailey)
Although this is an easy, hardy fish if kept properly, it is all too frequently portrayed as requiring bare tanks, dangerously high water temperatures, and special, usually unsuitable diets. The result is that many discus are short lived, highly stressed, neurotic wrecks.
What size: 6 inches in diameter
What minimum size tank?:
24X12X18 in for a pair, 36X12X18 for a community.
How warm?:
77-82 F
The tank recommendations seem VERY small....I mean I, like many fish lovers, would like to have 2-3 discus in my tank, but I think I will have to wait until I get a larger tank.
(My tank is 36X13X18)
What do you folks think of this info? It's weird, usually books have rock solid info but this seems a little strange...I don't know what to make of it.
