Even though Discus Fish are peaceful in nature, they may depict aggressive behaviour when breeding which can cause concern for other breeds in the community tank. When you place a group of Discus Fish, it is very likely that they pair off and start breeding. Upon breeding, your Discus will need a flat clean surface to spawn. This is the time when they become more territorial and start showing aggression towards others.

Cycling Your Community Tank
The most talked about topic when keeping a Discus is that of the Nitrogen Cycle. Nitrogen cycle comprises of three most important chemicals: Ammonia, Nitrate and Nitrite. Out of these three, ammonia and nitrite, be it in very small quantity, can be toxic for your fish. Nitrate, on the other hand, becomes toxic only when present in higher concentration.
When placing a Discus in community tank make sure you have the right cycling setup so as to avoid any mishaps.

Installing an in-line heater is highly advised. After heating comes filtration, Discus Fish require high quality water thus making a filtration tool highly important. If you install a sponge filter, it will not only help collect all of the solid waste but will maintain your tank’s nitrogen cycle.
Sensitive as they are, Discus Fish is prone to catching bacteria. This is why providing them with the right aquarium is essential. When in community tanks, they tend to catch diseases and infections.

Feeding Discus in Community Tanks
Feeding a pair of Discus is one thing, but feeding a whole community tank is completely different. First comes the diet, it is important to give your fish a mixture of fresh foods and commercial off-the-rack food.

Discus also likes to nibble on algae wafers or fresh vegetables. If their dietary need is met, they bloom and their colors become more vibrant.
After their diet comes the feeding ritual, Discus fish do not like to eat from the floating food or the one that settles in the ground. You might try feeding them right off your hand in the middle of the aquarium instead of just throwing the food. Another important fact is that they love to eat and snack around.
