Types of DiscusExtremely popular with breeders, discus have proved highly adaptable, with the four original wild species developing into a wide range of interesting varieties. Some of the most popular types of discus are as follows:
- Green Discus -This beautiful stripy green fish is particularly prized if it exhibits red spots.
- Brown Discus -Probably the easiest kind of discus to keep, this is also the easiest to find. It is comparatively adaptable and peaceful by nature.
- Spotted Discus -Increasingly popular in the aquarium trade, this comparatively hardy fish is available in several colour varieties.
- Red Turquoise Discus -This striking fish has a complex pattern of turquoise and red markings which are more vivid when it is in good health.
- Heckel Discus -This wild species is notable for the dark vertical stripe down its body. It needs warmer, more acidic water than most discus varieties, and is not recommended for the beginner.
- Pigeon Blood Discus -Golden bodied with distinctive black markings, this fish is also notable for its bright red eyes. Its black markings will become more vivid if it is ill or under stress.
Breeding DiscusSexing discus can be difficult, as there are no obvious differences between males and females - your best bet is to observe the way they interact with each other.
A pair of discus who are ready to breed will select a territory within the aquarium and begin to defend it from other fish. However, it is best to transfer them to a separate tank for breeding.
This tank should contain plants and vertical rocky surfaces for egg deposition. Change a small amount of the water in the breeding tank every other day and increase the supply of food.
