The Discus are generally found in large schools. They are very social in their behavior. They get along with other fishes very well. This also is another feature that makes them a must want fish in your aquarium. The Discus fish generally eats algae, insects, crustaceans, mollusks, and worms that live in water. In aquariums discus fish eat high quality flake food, pellets, blood worms, black worms and beef heart. Discus fish require a high protein diet.

Discus Fish breeding happens away from the school and take care of their young ones for about 2 weeks. Not very uncommon, but the Discuss feeds its young ones from a secretion that comes out through the skin. The parent discus will darken in color a develop a white mucus film over it’s skin that the fry will eat. During this stage it is very critical that you keep a close eye on the fish. Start introducing baby brine shrimp to wean the fry off the parents before they start scarring the parents skin. Once the fry are eating on their own and no longer attached to the parents then you can move the fry to their own grown out tank.

Discus have the reputation of being very difficult to keep. That is far from the truth. While discus are not for beginners that are fairly easy to keep as long as you have the proper elements and routine in place.

Discus require very clean water. Therefore it is critical that you have the proper filtration. In addition you must be able to dedicate time to performing water changes. The frequency and amount of water that you will need to change will depend on many factors including size of the aquarium, type of substrate being used, the amount of discus fish in the aquarium and the amount of plants and decorations in the aquarium. Unlike many rumors you will read online, it is not necessary to do water changes daily unless you are breeding discus. When you breed discus you have to do a least one water change per day at the minimum.

Discus fish are very compatible with other fish. They are slow moving fish so they like to be with other slow moving fish. Discus fish are also schooling fish. They feel safer in large numbers. Therefore it is highly recommended that you keep discus in groups of 6 or more. If you are hoping to get a breeding pair of discus then it is recommended that you get at least 12 discus fish. The odds of two of them pairing up is very likely.

Discus Water

Unlike your regular freshwater fish discus prefer warmer water. The best temperature to keep your discus in is 86F degrees. A safe temperature range is 84F to 86F degrees. Therefore you need to take caution what other fish you put in your discus aquarium being that your typical freshwater fish cannot survive in warmer waters. Discus can survive in temperatures up to 90F degrees. However it is not recommended that you keep the water temperature above 86F degrees.

    Hi Allan,
    Once the new tank is setup with fish yo need to do a daily check on your PH. Once the PH is stable then it is ready for discus. Usually 2-3 weeks on average.
    As far as how many fish- well it all depends on what size discus you plan on putting in there. For a fully grown 5-6 inch discus you want to allow about 10 gallons of water per fish. So at full size you are looking around 6 discus. However, when the fish are smaller around 2-3 inches in size you want to allow 5 gallons of water per fish. So you can get away with 10 (2 inch) discus. As they get larger you can move some of them to a larger tank or sell some for a nice profit.
    Feel free to contact me with any other questions.

    On another topic that you may be able to help or possible other discus people that have this same problem.
    Would be great to know how to kill/remove Trumpet Snails from my discus tanks. Tried all the methods off the internet to include clown loaches but the clown loaches have a issue with them picking on the sides of my discus.

      Hi Bob,
      You need to get yourself about half a dozen yoyo loaches. Yoyo loaches main purpose in life is to eat snails. They will take care of the problem for you. Clown loaches eat snails as part of their diet bu tit’s not their primary food. Yoyo loaches eat nothing other than snails! Yoyo loaches can be purchased online and in some pet stores. Good luck and let me know how you make out.
