A Reference Guide for Symphysodon Aequifasciatus
This is general information on Discus, a member of the family
Cichlid. Although certainly not a complete reference guide, it
will give those interested some background information on this
Symphysodon aequifasciatus (Discus)
Class: Actinopterygii (ray-finned fishes
) Order: Perciformes (perch-like fish)
Scientific Name: Symphysodon aequifasciatus
Other Scientific Names are: Symphysodon aequifasciata,
Symphysodon discus aequifasciata, Symphysodon aequifasciatus
aequifasciatus, Symphysodon discus tarzoo, Symphysodon
aequifasciata axelrodi, Symphysodon aequifasciata haraldi
Common Name: Discus
Range: South America: Brazil, Peru. Found on Amazon and
Solimoes rivers of Brazil, from the lower Rio Putumayo-Ica and
from Benjamin Constant to Belém. Has been introduced to the
Rio Nanay in Peru.
Diet: Carnivorous. Frozen foods preferred, but will accept
flake foods. Particularly like red bloodworms, but feeding "live"
food is not recommended. Red worms, etc, should only be fed to
discus once every other day. Beware of parasites or bacteria in
the discus tank from live foods!
Temperament: Timid of strangers. Easily frightened, unless
placed in a high traffic area. Can be very friendly to aquarist,
oft-times eating out of the hand. If given a place to hide, they
will tend to do so.
Sexing: Discus are hard to sex unless breeding. Normally, the
male will be larger, and will present with longer fin extensions
and a wider forehead.
Breeding: Buy either proven pairs or a group of young fish and
allow them to pair themselves. The eggs are laid on a breeding
cone. A clay flowerpot turned upside down works well. The fry
must be kept with the parents after hatch, as they "feed" off the
body slime of the parents. Special care must be taken to insure
that fry do not injure the parents when getting larger. Watch for
marks on the body of the pair, and if it begins to occur, the fry
are ready to be moved to a community tank on their own. If left
w/ the pair, serious injury can result.
Special Care: If kept specifically for breeding, a
bare-bottomed tank is highly recommended.
Other Comments: To keep Discus well, water conditions are
absolutely crucial. A PH of 6.3 to 6.9 is the optimal level for
keeping discus. Water Temperature: Discus like it warm. They come
from the Amazon basin, so water temps for these fish should be
80-84 degrees F, although some aquarists set the temperature as
high as 90 degrees F.
