Just wondering :) Would love to have some but have not been willing to sacrafice the $$ for them, as they are quite an 'elite' fish and I know they do not come cheaply.
You'll need a 55 gallons minimum for 6 discus. Discus are cichlids, yes but they are far less aggressive than some other cichlids.
They are not as delicate as you think. I have always thought about that but when I decided to keep them, it was actually the other way around. As long as you maintain the tank well, you won't have problems keeping discus.:)
They'll need a temp of 28-30 to thrive well. I must admit I don't use heater anymore because I live in the tropics and the heater, instead of help, killed several of my tetras.
Discus will adapt to your water stats so pH is nothing to worry about.
You'll need to vary the food menu as they receive different nutrients at that. The same applies to other fish.:)
