A small presentation to know which fish are you kept with discus. From this presentation you know more about discus. Follow me for more updates about pets.

3.  Cardinal tetras are probably the best companion fish for your discus
aquarium. First of all, a group of cardinal tetras are simply beautiful tropical
fish. They are fun to watch. Cardinal tetras are also very suitable with the
warm, acidic water that discus like. Finally, cardinal tetras are dither fish.
Dither fish can have a strong calming effect on more timid, larger fish like
discus. The small dither fish swim back and forth in the aquarium, out in the
open. The discus notice that these small fish seem secure in their
environment. That gives them a signal that everything is safe in their
enclosed environment and allows them to come out into the open without
any fear. If you ever have shy, skittish discus that always seem to hide, you
might want to add a school of cardinal tetras to your aquarium.

4.  Corydoras catfish are another good fish to add to a discus tank. Adding a
few corydoras catfish to the tank will help with clean up maintenance. They
will scamper around the aquarium looking for any particles of food that have
not been eaten. This will help keep the aquarium water cleaner and your
discus will be much happier for it. If you add coryadoras to you discus
aquarium, try to keep the water temperature around 82 - 83 degrees. Corys
don't like the higher temperatures.

5.  Ancistrus are also suitable tank mates for your discus. These fish will help
keep your tank clean by eating the unwanted algae that forms in your
aquarium. Make sure you supplement the ancistrus's diet with some quality
algae wafers on a regular basis and add a small piece of driftwood in your
tank to help them digest their food.

6.  Other suitable tank mates for discus include: clown loaches(make sure they
have a place to hide in the aquarium), German blue rams, rummy nose
tetras, glowlight tetras and rosy tetras.

7.  You should avoid keeping large tropical fish that can intimidate discus or will
compete aggressively with them for their food. Fish like oscars, piranhas,
severums and flowerhorns fall into this category.

8.  Angelfish is another fish that should not be kept with discus. They are too
aggressive, especially when they reach sexual maturity and will try to take
over the entire tank forcing the discus to hide. Angelfish are also very quick
eaters and might cause your discus to miss out on food.

9.  Avoid fish that don't like warm, acidic water
that discus prefer. So don't put any African
cichlids in with discus. Also don't put neon
tetras in with discus since they prefer much
cooler water.
 Finally, don't put in fast swimming, fin
nipping fish. Fish like tiger barbs, danios or
tinfoil barbs will damage your discus by
nipping their fins and will make them very
skittish.

10.  Discus breeding pairs should be kept alone. They might spawn in a
community tank with other fish, but the fry will almost never survive. If the
other fish in the aquarium don't eat the discus eggs or wigglers, the discus
parents usually will, to "protect" them. Always keep discus breeding pairs
alone in their own aquarium.

11.  Remember that discus are shoaling fish and do best in groups of 5 or
more. They feel much more secure and have less stress in large groups.

12.  Finally, never add young, small size discus into an aquarium with
significantly larger discus. The larger discus will bully the younger fish
causing them stress. The larger discus will also aggressively eat most of the
food causing the smaller discus to go hungry, get weaker or sick. Over time,
the bullying of the smaller discus might cause them to become stunted.
Grow smaller discus into a separate tank and then add them with your larger
discus when they are close to the same size to avoid any problems.
