I feel that under optimum conditions, discus
might live 10 to 12 years or so, but most won’t
reach that extreme age. In our hatchery, we’ve
had discus that have reached 8 years, and in a
few cases, some of these fish continued to breed
at 6 years of age.
I have what I consider to be good water
for discus. How often should I change this
water for my discus?
If one does have good discus water, I would
make an effort to make daily changes of 40
percent. If priorities don’t allow daily changes,
then twice-weekly changes of 25 percent or
more should be satisfactory. As always, the
more water changed, the better, and the more
often it is changed, the better.
How often should adult and young discus
All of our adult discus are fed once daily,
omitting a feeding once every ten days or so.
However, all younger, still-growing fish are fed
at least three times per day, without skipping
Are brine shrimp a nutritious food for
My opinion is that Artemia (brine shrimp)
in any form is an overrated food for discus.
For the most part, it consists of an exoskeleton
and a body that is mainly water, but many
Do earthworms make a good food for
discus and other cichlids?
MP. & C. Piednoir
Discus should be kept at temperatures of about 82° to 84°F, and a pH of about 5.0 to 6. 5, to help
keep them happy and healthy.
Live tubifex worms can be carriers of harmful
pathogens for all tropical fish, regardless of
how carefully they’re washed. Therefore, I’ll
suggest that you shouldn’t feed them to your
discus at any time. There are so many good
alternative foods available that it just isn’t
worth the risk.
There’s probably no better food for
conditioning discus and other new world
cichlids than small live earthworms. Initially,
the worms are not generally accepted, but
discus can be weaned onto them after several
feedings. The most eagerly accepted worms
are those that are an inch or two in size.
They are very nutritious, and being terrestrial
and not aquatic, they don’t carry the harmful
pathogens that many other worms fed to
tropical fish can have.
Is beefheart a necessary ingredient in
Much controversy surrounds the use of
beefheart as a food for discus. If the beef has
not been subjected to harmful hormones, it’s an
excellent food, and it contains all the essential
amino acids that are necessary in discus diets.
It can be a very useful ingredient. However,
many quality discus diets do not contain
Live Tubifex Worms
Are live tubifex worms suitable as food
Should vitamins be added to the water in
Though adult breeding discus require softer
water, young growing discus should be
provided water with a hardness reading of
700 to 800 microSiemens or more for proper
tissue and bone growth.
Vitamins are important for all tropical fish,
but they should not be added to the water. They
should be added to the food at the time of the
feeding, if possible.
