Okay .....should I listen to you or a Professor of Biochemistry who just happens to specialize in fish nutrition, genetics and by the way . . .he is a professional Discus breeder since 1988
He is really schooled when it comes to Discus. He advises to put them in smaller tanks and grow them up instead of having a small Discus that's in a 4ft and sits in the corner, not getting the sufficient food supply. He wont eat unless he is competing with other Disci for food. So unless you have 50+ of these fish in a 4 foot, the chances of the fish living 1 month is very low. You should forget about keeping Discus if you are considering keeping just one or two.
Do you even know about Discus behavior? It's not just about size of the tank its about feeding and getting the water parameters just perfect. It's also about the overall environment and well being of the fish. You cant force him to eat. Smaller Discus are more difficult to take care of. Bigger ones are much less a worry. That's why its recommended to raise them in a smaller tank where there is less room and more competition.
He recommends that people start taking care of Blue Rams first because their requirements are exactly the same except the Rams prefer a minimum temperature of 26*C (79F) and Discus a minimum temperature of 30*C (86F). If you cant take care of rams, forget about Discus completely.
It is not advised to keep Discus in a community tank because of its high temperature requirements.
From what I've seen, his Discus are of a very high standard.
kitten_penang .. Have you ever owned a Discus or any of the other fish in the threads that you comment so readily on?
If I had not read through Prof Dirk Bellstedt's experience with Discus, I would have gone out and bought a Discus and it would have died.
There are specific requirements for Discus. From the volume of your filter, type of filter media, type of filter, flow rate,substrate, water parameters, feeding, food types, plants , tank size, number in a shoal, lighting etc.
If these variables just happen to be misread or misunderstood, the dream of raising a shoal of Discus to adult hood will be short lived.
Just a heads up to people already keeping Discus. Some of you may find it easy to raise but you may be raising an unhappy fish. Just follow the link and hear it from an experienced breeder who has more to say than what's been advised...we all can learn from this! Dirk U. Bellstedt's advice on Discus
