I have had fish for 20 years but still haven't attempted discus. I don't mean to suggest they are particularly difficult, they are not, provided you recognize their specific wants and provide them. Temperature is one thing that has held me back; they must have warmth, above 82F, which many other tropical fish cannot tolerate long-term, so tankmates must be chosen with equal care.

One suggestion on discus, always get them from a breeder as close to you as possible. First, they will be more likely adjusted/accustomed to your tap water parameters with less fussing (and that is a big issue). Plus, local breeders frequently are a wealth of information and help along the way.

There is no need to do 100% water changes daily on discus tanks unless you are breeding them; as 1077 and kymmie will I'm sure attest, normal but regular and thorough water changes in a well-planted tank will suffice. But they are not a fish that accept lapses in aquarium management. Discus are still expensive (for good fish; those you see for $30 in the store may well be at death's door so to speak) and before laying out $100 or $200 per fish, you want to know your stuff. Like I said, I haven't gone down this road--yet.

Byron.

the 100% water change is due to people feeding the discus beef that's been badly prepared that causes the water to turn stale in a matter of minutes and has oil in the filtering system and on the surface of the water.done right a 20% water change each time beef is given as a snack ( not and everyday thing) it's a once or twice monthly thing.

(I've never kept discus, so take this with a grain of salt. I've done a bit of readon on the subject though.)

The only reason for the massive w/c's, are because of the Beef heart. Professional breeders feel their fish beef heart to 'bulk' them up, and induce them to breed.

Personally, I prefer my tanks to mimic nature- Do you think a Discus in south america has ever come upon a dead cow, and then proceeded to eat it's heart?

You CAN keep a pair of discus in a 40, but it's true they might not reach full size. By full size, I mean the wize they get to if they eat lots of beef heart.

The bare minimum, according to several sources, is 10 gallons of water per fish. I'm not sure I agree with that, because it's calculating a group. Something like a 60 G for 6 still seems overstocked, but I've seen pictures of a 40G with a breeding pair. They only grew to about 9 inches long, but seemed healthy and spawned multiple times.Temperature was 80 degrees, heavily planted.

Many fishkeepers hold their Discus at 82-84 degrees to avoid illnesses and speed growth, but according to fishbase that's NOT the temperature in their native enviroment. I suppose it would depend on whether you got a wild-type or a super-colorful captive bred (in-bred) species.

Ahh, only the captive bred (in-bred) fish are the colorful ones? Are there other health issues because of that. I am thinking of the Blood Parrots that I first thought were so great only to find out the horrid things that were done to these fish to make them look that way. I thought the Discus were naturally colored all the bright colors.

It's one thing to selectively breed fish to create various colour strains, quite another to inject dyes and various other stuff to create deformed fish like the blood parrots. Discus are not harmed by selective breeding. So while one wouldn't find these colour forms in the wild, they are not unhealthy for that reason.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Alright, Thanks Byron. There are some very strikingly beautiful colors for the discus. I am glad to hear they do not do something cruel to them to make them that way. It was disheartening to hear that the Blood Parrots are that way. I thought they were really cute fish and I considered getting a few myself. I have since changed my mind. I guess I don't wish to promote that type of thing in animals. It is something I have fought against in purebred dogs for years.

I think I am going to leave well enough alone with the fish I have stocked in my tank for now. Maybe think about adding a few shrimp for tank cleaning but then just let things be for awhile.
