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 7.0 and better (6.3 to 6.6) 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 â€“ 86F.
Another point to cover is that Discus
are best suited to large deep aquariums as they commonly grow to around 6 or 7 inch. They prefer to be in shoals of no less than 6 when they are growing up.
They can be kept in bare tanks but benefit from bog wood and plants as these help the Discus
feel safe knowing they have some where to hide. If they get stressed and scared in a bare tank they can dash around and damage there selves.
Ideal tank mates for Discus
include small tetras from South America i.e. neon tetras. They are also ok with various cat fish and plecs but please make sure the Discus
is the largest fish in the aquarium.
hope these helps
