I've been researching discus fish and have decided I want some of the these amazing fish, maybe the blue or green variety. Does anyone here currently own any? Any pointers you can give?

I already know they need soft, warm water, can't tolerate bullying and known for being hard to keep. I was wondering how much space say 2 or 4 would need? I wouldn't be getting them straight away as I'll either need a bigger tank or sell off some current fish. Another thing, I've also seen them in red/ pink and yellow in colour, is this natural or been bred?

Discus thread in general too.

No one?

What would convince you to own some?

I know your down with the whole no filters/ heater thing, do you think it could work with these fish?

the above pic is a blood pigeon . its a man made colour. i have a couple of those along with a few others. generally u need around 10 gallons per fish. very good filtration . in the order of 10 x tank capacity per hour , also you will need water changes twice a week aside from that they are very easy to keep. avoid any chemicals. have the temp around 29 and ph 6-7 im lucky my tap water is perfect .
