the discus based forums make these fish seem like so much work, but they're such attractive fish.
Yes, I have pressurized CO2, and driftwood, and R/O DeIonized water to help keep the PH down. Water changes must be at least weekly (some do it more often). Temperature must be kept warm. I have 2 heaters. I probably need 2 but, even if I didn't need 2 it's nice to have the second one for backup in case the other fails.
I don't think they are that much extra 'work.'
They prefer frozen food over flakes and pellets, but will eat those also.
Some say. one Discus per 10 gallons. I can go along with that - at a maximum. They are best kept about 6 at a time, and are less timid when they have others around. I wouldn't get just one or two...
I think they get around 6 - 7 inches..
