Are you thinking about getting some discus then and want to know a little about them. Have you been to the aquatics and seen some lovely colourful discus in there show tanks. A lot of people will tell you that discus are only for advanced fish keepers but in my experience they are easy to keep as long as you follow some basic rules.
First of all, discus require clean water free of chlorine and heavy metals. You may be best to invest in a water purifying unit. Make sure the water is on the soft and acidic side. pH between 6.0 and 7.5 with a general hardness between 5 and 15. Now is you want to been them these will have to be lower.
The water should be well filtered but slow moving and be heated at around 82
