The Discus fish is known as the King of the Aquarium. Perhaps the most beautiful of all tropical fish, the Discus fish is also one of the more difficult tropical fish to keep and is not recommended for beginners. Discus require excellent water conditions, frequent water changes and higher water temperatures than most other tropical fish. Most successful keepers house their Discus in a species only tank because of the high water temperature requirement.
There are many color varieties of Discus to choose from with many more being introduced all the time. If you are interested in this fish, be prepared to spend some jack on this one of a kind tropical fish. If you're on the market to buy Discus, there are many online websites that specifically sell Discus. Shop around and get recommendations from others for good places to buy them.
Many fish keepers will only get the best available foods for this fish. Vitamin enriched flakes and live, frozen and freeze dried foods can be given.
See the Discus Care Sheet on the forum for more details on keeping Discus. While on the forum check out the buy and sell board to see if there is any discus fish for sale if interested.

Discus Fish Tips
I want to know more about the difference in sex of discus in detail. How to differentiate them on sight?
|Determining the sex differences just by looking at them is nearly impossible unless you are witnessing a spawning pair. Unfortunately the most accurate way to determine gender is when they are forming pairs and actually breeding. |
However, there are some theories out there that suggest the males are usually bigger and more colorful than females from the same spawn (same age). If you are trying to get pairs, a good approach is to buy 6 or 8 at a time and hopefully the odds of getting a pair will play into your favor.
How long will Discus live?
|If kept in optimal conditions, their lifespan can be 10 years or more.|
At what age do they breed and at what size?
|Discus reach sexual maturity sometime between the age of 18 and 24 months. You will know they are ready to mate when they form pairs and begin to clean a spawning site in your aquarium. They will continually pick at the spawning site until they are ready to release and fertilize the eggs.|
Can young discus and young angel fish be kept together in a 55 gallon tank?
|Though I've heard it being done and I have also seen them kept in the same tank, it is not recommended to keep Angelfish and Discus in the same tank. The reason being that Angelfish can sometimes carry intestinal parasites that can be transmitted to your Discus (reference: Discus Breeding For Beginners, By Jack Wattley).|
Hey, I currently keep two angels with my discus, but they're all fairly young currently. So far, no problems at all. In fact the smallest Discus swims with the angels and they seem to look after it! I fully intend to split them up when they get a bit larger though. No point risking these beautiful fish.
|From: Juan and Sylvia - Discus Filter|
What would be the best filtration for the discus? Would an external mechanical filter that hangs on the back of the aquarium with carbon filter pads be good enough?
|An external power filter that hangs on the back of the tank should be fine. Discus require really good water quality that is best achieved via frequent small partial water changes weekly with better results achieved with daily partial water changes. Keep the media in any filter you use with your Discus frequently cleaned out too to prevent nitrates from getting too high.|
