Now that you have quite a lot of the tropical fish here I would like to introduce another tropical fish. This fish is called King of the Aquarium Fish, Freshwater Discus Fish. The discus are exotic and less prolific compare with Angelfish.

Symphysodon Aequifasciatus

Symphysodon Aequifasciatus

The two distinct species of this colorful fish present are the Symphysodon Aequifasciata and Symphysodon Discus. The Symphysodon Aequifasciata includes three subspecies commonly known as the Green Discus, the Brown Discus and the Blue Discus. The body shape of Symphysodon Aquifasciata is almost round and their basic color ranges from greenish brown to yellowish brown and have nine vertical bars or stripes on the body with a beautiful iridescent blue to greenish blue pattern on the head, the back and the fins.

Symphysodon Discus

Symphysodon Discus

This fish can grow to a matured length of 12cm whereas the Symphysodon Discus is slightly more elongated. The color is reddish brown with nine vertical bands on the body with a lovely pattern of bluish green iridescent lines across the head, body and the fins. There are no external sexual characteristics in the discus.

The fish will pick their own breeding mates and their eggs are laid on a large piece of cylindrical earthenware pipe or driftwood place below the surface of the water. If you have the Amazon Sword plants planted in the aquarium is also a good idea for the discus as they choose to lay their eggs on them occasionally. The water pH value for breeding the discus should be 6.0 and soft and acidic.

The eggs takes about three days to be hatched and the young fry normally hang on the aquatic plants or driftwood and they get the nutrients from the yolk sacs. They will cling themselves to the bodies of their parents by feeding on the mucus secretion secreted by their adults. The larger fish fry will feed on brine shrimps while the adult fish feed on tubifex worms and bloodworms.

Description About Discus

Discus fish is a genus of the cichlids nature to the Amazon River Basin in South America. They are call King of the Aquarium Fish where Symphysodon is the scientific name and colloquially known as Discus. The round body of discus are associated with their habit of staying mostly in protected areas that are heavily vegetated or have abundance of exposed tree roots allowing them to slip between plants with ease. They are also very shy and are active only at night so it is best to keep in groups and need to be taken care of in a proper manner in the aquarium.

Scientific name: Symphysodon Aquifasciatus

Habitat: Amazon Basin of South America

Common name: Blue Diamond Discus, Dark Brown Olive Green Discus

Adult length: up to 4.7 inches (12cm) often larger (6-7 inches)

Tank length: 50 gallons water

Ideal water temperature: 77 – 86 degree Fahrenheit (25 -30 degree centigrade)

pH Range: 6.0 – 7.2

Nutrition and Diet: carnivore so feed on frozen bloodworm, crustaceans, plant matter, insects and live black worms

Choose the right tank size of about 50 gallons water with 48 inches length and a 24 inches lighting with a proper biological filtration system. Clean water and nutritious food requirement is a must. Discus are calm, silent and timid in nature therefore it is advisable to keep them in groups of five or six sometimes up to ten  but again this depends on the size of your tank. Discus are quite a large fish when full grown and you can also add companions of their choice. Care must also be taken in choosing their tank mates.

 

Tank Mates for Discus Breeding Pairs

Discus breeding pairs should be kept alone because during spawning, the fry will be swallowed up by other tank mates in the community tank. They will never have the chance to survive. Always keep discus breeding pairs alone on their own aquarium because the discus parents will protect them when young.

Discus are shoaling fish and they are best kept in groups together in five or six or more and this makes them feel much secure and have less stress. To differentiate male and female Discus, male Discus come with longer ventral fins compare with female Discus. The male Discus’s behavior will be distinguished by their action during spawning.

Finally I would advise that small size discus are not to be mixed with larger ones in the same aquarium because the larger ones are more aggressive during feeding and the smaller ones are weaker so they will be starved and underfed. You may also keep the smaller ones in a separate tank and then add together to the larger ones in the same tank when they grow to about the same size of the larger discus to avoid any problems arising.

During breeding, the adults will produce a secretion through their skin in which the young depends on during the first four weeks. During the first two weeks, the parents will stay together with their young allowing to feed them easily. In the last two weeks the parents will swim away leaving their young to fend for themselves gradually.

The sexual maturity for discus takes one year. The primary food for Symphysodon is algae and other plant materials whereas in the wild they feed on invertebrates. Unlike other cichlids species the Discus have large intestines and they are herbivorous or omnivorous.
