Discus

Discus are found in the varied tropical waters of the Amazon River in South America. The Amazon river contains water known as white, black or clear. It's in the areas where these differing water meet that Discus are found. The Discus is considered a fish for advanced fish keepers and thrives on planted aquariums. They certainly are stunning fish and one of the most instantly recognisable.

Discus aquarium condition requirements

Temperature - Discus fish like water kept at high temperatures 28o/30oC 82o/86oF is usual although there is some variation in nature. The best water conditions are soft and acid. Low hardness with a pH of less than 7 is ideal. Good filtration without too much water disturbance.

Habitat - gravel substrate (preferably lime free) with a well planted tank of large plants such as Amazon Swordplants (Echinodorus spp). Bogwood with growing plants attached is fine.
