Discus Care Guide

King of the Aquarium

Discus are members of the Family Cichlidae and are sometimes referred to as “King of the Aquarium” because of their majestic beauty and regal colors. At least three species have been described, although debate continues over the validity of several assigned scientific names. Wild caught discus can be challenging to keep, due to their specialized water chemistry and dietary needs, however, most discus sold today are captive bred and are much easier to keep. That said, they are not for beginners for a variety of reasons. Through selective breeding, numerous color varieties are available and more continue to be developed. For care and maintenance purposes, the information presented here can also be used for wild caught P. scalare and P. altum angelfish, as well as Uaru.

Natural Habitat for Discus

Discus are found in floodplain lakes and flooded forests of the lowland Amazon River basin and some of its tributaries, including the Rio Negro. These areas experience extreme changes in water level due to seasonal flooding. Discus tend to congregate near fallen trees, known as “galhadas”, along the shore. They prefer quiet water and are rarely found in areas where there is strong current or wave action.

Discus Water Requirements

Discus prefer warm, soft, acidic water. pH should be between 6.0 and 7.0, with hardness between 1° and 4° dKH (18 to 70 ppm). Temperature should be kept between 82° and 86° F, although wild Heckel discus prefer water near 90° F. Use an Aqueon Aquarium Heater to maintain proper water temperature. While captive bred discus can be kept in dechlorinated tap water, reverse osmosis or deionized water supplemented with Aqueon Water Renewal will provide the best conditions. When purchasing discus, always ask about the water chemistry they were raised in. Discus require pristine water quality, and weekly water changes of 10% to 25% using an Aqueon Aquarium Water Changer or Siphon Vacuum Gravel Cleaner are highly recommended. Don’t forget to treat tap water with Aqueon Water Conditioner before refilling your aquarium!

Housing Requirements for Discus

Discus grow to be quite large and require an aquarium of 75 gallons or larger when full grown. Tall aquariums are best to accommodate their body shape. Water movement should be gentle, and décor should include large broadleaf plants and driftwood that is arranged vertically to simulate downed branches and trees. A few floating plants can also be added to provide shaded areas and cover. Substrate should be sand or fine to medium grade, smooth-surfaced gravel as discus like to forage along the bottom for food.

Discus Behavior/Compatibility

Discus are generally calm, peaceful fish, but as cichlids, they can be aggressive toward one another, especially when attempting to pair off and spawn. Shy or submissive fish should be removed if they are unable to compete. Most serious hobbyists do not mix their discus with too many other species. Some suitable aquarium mates include cardinal tetras, neons, emperor and rummynose tetras as well as clown loaches and dwarf cichlids, such as rams and Apistogramma species. All of these fish tolerate the high temperatures and low pH/hardness required by discus.

What do Discus Eat?

In nature, discus eat a considerable amount of plant material and detritus, but also forage along the bottom looking for worms and small crustaceans. They are omnivores and will thrive on Aqueon Tropical Flakes, Color Flakes, Spirulina flakes, Tropical Granules, Algae Rounds and Shrimp Pellets. Frozen and live foods should also be fed as treats or to help induce spawning. Some hobbyists and breeders feed their discus beef heart, and while it is not harmful, it is certainly not a natural food for discus. For best results, rotate their diet daily and feed only what they can consume in 2 to 3 minutes, once or twice a day.

Discus Breeding Level – Difficult

Captive bred discus will pair up and spawn relatively easily, but young, inexperienced parents may eat their eggs the first few times, particularly if other fish are present. After hatching, the young feed on heavy body mucus secreted by the parents for a few days until they begin to free-swim. Parents will transfer the young back and forth several times a day.

Stocking Up A New Discus Tank

Stocking Up A New Discus Tank

So you have decided to buy a new tank and you wish to keep discus in it. So how do you mature the filters And how long before you can add your discus stock.

STEP ONE: – SIZE IS EVERYTHING

The first thing to consider before you even buy the tank for your new discus is how big it needs to be. You will need to allow ten gallons for each discus. Also discus being a shoaling species a minimum number of at least six discus will need to be kept.

So with this information so far we can see that a tank of at least 60 gallons will need to be used for keeping discus. The only exception for this is if you have a bonded breeding pair. Even then it is very wise to place the pairs in separate tanks along side each other so they can see other pairs in the neighbouring tanks. Time and time again I hear of small tanks being used for keeping discus and two or three small fish being kept and then the keepers reporting that the discus are shy, hiding away, turning black or not feeding. Small discus especially will sulk if not kept in numbers of at least six, the more the better. Larger ones tend to not be so bad if kept in small numbers but will still need to be kept in good numbers for best results. I have always found that the bigger the group the less squabbling and fighting there is.

STEP TWO: – SETTING UP

With the tank size determined and stocking levels planned how soon can you add your new discus Time is the key word here, because this is what you will need to mature and colonize the new biological filtration system. This is a very debatable area as it is possible to cheat here and I myself have had to do this in the past to get tanks up and running as soon as possible. Being a retailer time is also important and the sooner the tanks are running the better. Ways of speeding up the maturing process are numerous, some to name a few are placing mature filter sponges from old tanks, and then these can be squeezed out into the newly set up tank. When this is done approximately 95% of the beneficial bacteria is washed out into the new tank and is consumed by the newly running filters onto the new media, and hey presto. A good start for a breeding ground for the new colony. Other ways can be done by siphoning off dirty water from a mature under gravel tank and then adding the water to the new tank. Also good additives can be bought in a bottle to colonize the filter. But the best way and the old favorite is doing it like this. First set everything up and fill the tank with treated tap water or better still use an RO unit or water purifier and run the tank for 24-48 hours. Ammonia or waste fish products will need to be present so the cycle can begin. It would be no good running a tank with nothing in it and then adding the discus after weeks or months. Because ammonia would go up which would burn the gills of the fish which could make them dash about and may even cause disease or even death.

STEP THREE: – THE BEST WAY.

The best way to stock a new tank for discus is to set everything up, fill with treated water as described in step two. Add stress zyme or a similar product to help keep down the ammonia levels, protect the fish and help the maturing process. First buy a small group of tetras and add to the tank. Over the weeks increase the size of the group and if you want to add different ones like cardinals, neons, glow lights, rummy noses etc.Keep a good check on the ammonia and nitrite levels, if they rise do a water change to help the new filters. When you see a rise in nitrate you know that the new filter is working, i.e. ammonia is being broken down into nitrite and then into the third less harmful nitrate. Water changes on a regular basis will help to keep down the nitrate. As you build up the stock keep an eye on PH, as with the stocks growing waste products from the fish will make the PH drop so may need buffering up. After a week or so bottom small feeders like Corys or L plecs can be added. These are ideal as a cleaning gang to clear up after the messy discus. If after 6-8 weeks it is possible to add some discus, if all water perimeters are correct.

STEP FOUR: – HOW MANY

This may sound not so important but how you add your discus is very important. Many think it is good to add a few discus and slowly increase over a period of time. Unlike the tetras it is a good move to add at least six discus at the same time. The reason as already stated is the problems with discus in small numbers; also if you add them at the same time they can sort out a pecking order and settle down. If you add more at a later date you may have problems settling in new comers with a group already established.

CORRECT WATER PARIMETERS FOR KEEPING DISCUS.

AMMONIA: – ZERO NITRITE: – ZERO NATRATE: – AS LOW AS POSSIBLE, HIGH LEVELS NOT SO IMPORTANT. PH: – 6.3 – 6.5 CAN BE AS HIGH AS 7 FOR SMALL DISCUS. KH: – 3-4 GH: – 3-4 TEMPETURE: – 86 TDS: – AROUND 125

TOP TIPS (DID YOU KNOW)

It will take at least six months to fully mature a new filter system. Stocking with smaller discus will put less of a strain on a newly set up tank. Because discus need temperatures up in the mid 80s make sure you have plenty of air stones. (High temperatures = less dissolved oxygen levels) Do not use bright lights unless you have floating plants, discus like subdue lighting. Make sure you have good tight fitting covers on the top of the tanks. Discus can jump out of tanks very easy.

Think T.I.M.E.

T. Is for time, taking plenty of this will insure better success.

I. Is for invest in the best equipment for your discus.

M. Make sure you keep a check on water quality.

E. Enter discus specialist shops only, they will be able to help if you have any problems or questions.

Discus Care Guide: How to Keep a Discus Aquarium

(

) and Team Buce Plant

Written by: Tammy

Often known as the “king of aquarium fish,” discus earn their title through their gorgeous colors, patterns, and variations. Particular strains of them are highly sought after, and some can easily reach a price of hundreds of dollars for just one.

Even though this species of fish is so beautiful, they are not as commonly found in the hobby as other fish. This is likely because there is another connotation about discus being one of the most difficult freshwater fish to keep. While discus fish care may require more attention than other aquarium fish, the thought of owning discus should not intimidate experienced aquarists. As long as they are kept in ideal conditions with routine maintenance, there should be no problems.

Tank Size

While it’s possible for discus to reach a length of 9 inches, this is only if they’re kept for a long time in the best conditions possible. Most discus in the common aquarium max out at 4.5-6 inches.

Based on this size range, the minimum tank size would be a 55 gallon tank, but the bigger the better for these guys. 3-5 discus should be doable in a 55gal aquarium as long as water changes are kept up with. A general rule you can follow is one discus per 10 gallons. Since these fish are tall, do not keep them in shallow tanks. The UNS 90U, 120P, and 120U are all high quality aquariums that would be great for discus!

Filtration

Good filtration is necessary to keep the aquarium clean and make sure the water is chemically clean. Discus fish will not do well in tanks where nitrogen levels are spiking or unstable. Make sure the aquarium is fully cycled before adding them in.

Since these fish are usually kept in larger tanks, stronger and bigger filtration might prove to be better. Sump filters are great for large aquariums, but can be hard to set up. A great option to consider is a canister filter like the UNS Delta 120 or Delta 90. Canister filters hold a lot of media for necessary beneficial bacteria and usually provide a current that is strong enough to pull the debris from the tank into the filter. Just make sure to clean the filter regularly!

Water Parameters for a Discus Tank

Temperature

Water quality and parameters are important when considering keeping discus. Unlike most other tropical fish that prefer water temperatures of 78F or lower, discus like it warmer. Depending on how you’re keeping your discus, different temperatures may be more suitable for your setup.

For keeping discus in general: 84F-86F

84F-86F For raising young or growing juveniles: 86F-88F

The increased temperature will speed up their metabolism, allowing for more feedings and faster growth.

86F-88F The increased temperature will speed up their metabolism, allowing for more feedings and faster growth. For breeding or keeping in a planted tank: 82F

The lower temperature mimics the natural environment of the Amazon’s rainy season, stimulating them to breed.

Keep in mind that most aquarium plants don’t do well in hot temperatures. You must consider hardy plants such as bucephalandra, anubias, and java fern, and give them time to adapt to the warmer temperatures.

Note: When maintaining a planted aquarium with high temperatures, aeration is very important. The warmer the water, the less ability it has to hold oxygen, so make sure there’s enough oxygen for the fish by installing an air pump if necessary.

pH & Hardness

Discus prefer soft, acidic water. Ideally, a pH of 7 or below and a gH of 1-3 is what many strive for in a discus aquarium. While this is probably best for them, it’s not impossible to keep healthy discus in higher pH/hardness levels. They’ve been bred in different water conditions around the world and are capable of adapting to other ones. In general, a pH of 7.5 or less and a soft to medium hardness level will work just fine.

Why a Planted Tank is the Best Idea

After going through all the preferences for a discus tank setup, the conclusion is that planted aquariums could be considered the ideal setup for discus because they help achieve the ideal conditions for keeping discus.

Arguably, the best filtration for aquariums are aquatic plants! Plants will absorb ammonia and nitrates right out of the water when they grow, chemically cleaning the water. More plants and carefully injecting CO2 to help them grow will filter the water even more.

Aquatic plant substrates like UNS Controsoil are not only designed to help plants thrive, but they also stabilize and buffer the pH to optimal levels for most tropical fish. Planted tanks that use these nutrient-rich substrates are more ideal for discus than bare bottomed tanks.

Driftwood, a common type of hardscape to use in an aquascape, also lowers the pH and hardness of the water.

The greens of the plants will contrast the colors of the discus, resulting in a beautiful pop of color.

Maintenance is Important!

Heads up: you cannot slack on tank maintenance when it comes to discus. Even if you have a planted tank, a weekly water change of at least 20% should be performed. Approximately 40% or more in a non-planted aquarium. It really depends on how many fish, the bioload, and the size of the tank. Make sure to siphon out as much detritus as you can during each session.

Diet

Discus can be picky eaters, so try to feed a variety of foods like flakes, pellets, and frozen/live foods. When it comes to how often you should feed your discus, feed them no more than 3% of their body weight. On average, adult discus (1+ years) should be fed 2-3 times per day. When feeding, make sure you have clean hands free of any lotion or hand sanitizer.

Changing up the types of food you feed will prevent them from sticking to only ever going after one food. If you receive new picky discus, but you want to feed them flakes instead of bloodworms, slowly introduce the new food (ex. flakes) while also feeding their original food (ex. bloodworms).

Tank Mates

Friendly/non-aggressive community fish that are big enough to not be seen as snacks should do well with discus. Freshwater shrimp can be too stressed in an environment with discus, but it depends on the scape and whether they have ample area to hide and explore without being bothered by the discus.

Keep in mind, any fauna you add to the tank need to be able to handle the hot temperatures that discus like to be kept in. They should also be fast enough to avoid getting eaten by discus, but not so fast that they outcompete them for food, as discus can be slow when it comes to eating. Great examples of tankmates are cardinal tetras, rummynose tetras, sterbai corys, small plecos, and rams!
