Guppy Origins and Environment

Guppies are native to areas around the northeast side of South America. Which include Antigua and Barbuda, Barbados, Brazil, Guyana, Netherlands Antilles, Trinidad and Tobago, the U.S. Virgin Islands, and Venezuela. To better re-create a guppies biotope in an aquarium, you'll probably want to research the Amazon River and Rainforest areas.

You'll find such plants like Amazon Swords at your local petstore that are obviously native to the Amazon. Other native plants are Sagittaria, Ludwiga, Syngonium, Myriophyllum, Caladium, Orchid, Giant Water Lillies, Anthurium, Bromeliad and Cabomba to name a few. Other South American fish you may come across locally are certain cichlids, discuss, angelfish, rams, cory's, oscars, tetras, barbs, gouramis, and killifish. Your best bet to re-creating that rainforest feel in your aquarium is to also check the reptile isle at your local petstore as they have lots of rainforest/jungle inspired decor which you may be able to use in your aquarium.

Keep in mind that South America consists of (3) major water types...whitewater, clearwater (blue water), and blackwater.

(1) Whitewater rivers pick up large amounts of sediment from the Andes giving the water a muddy-brown color. Whitewater receives its name from the white foam of the rapids of the upper regions. Whitewater rivers lack abundant plant life. Most aquarium species are found in quiet, backwater areas like oxbow lakes. The water properties of whitewater rivers are a pH from 6.8-7.1 and a dH of 3-5. The best example of a whitewater river is the Amazon River.

(2) Clear or blue water rivers are tributaries which flow through ancient Brazilian and Guyana rock beds where little sediment is released into the rivers. The water of these rivers is very clear and allows plant growth. Clearwater rivers have a pH of 6.9-7.5 and a water hardness of 5-12 dH. The Rio Xingu and the Rio Tocantins are such rivers.

(3) Blackwater rivers are nutrient poor and tea or black in color from the tanic acid released from decaying vegetation. Blackwater has been compared to distilled water due to its lack of dissolved minerals. Blackwater rivers are acidic and have a pH of 6.0 with little measurable water hardness (0 dH). The Rio Negro is the most famous of the blackwater rivers.
