Aquarium filtration systems, how do they work?

Before you enter any store asking for advice about which filter will suit your aquarium. We recommend you go armed with this basic knowledge about filtration systems. This will help you to make an informed decision and it will save you from future headaches. Let’s start by understanding what filters are designed for.

Denison's Barb (puntius denisonii) a controversial species

Originating from the fast- flowing hill streams and rivers of the state of Kerala and South Karnataka in South India. They can grow up to 6 in (15 cm) and have a life-span of 8 years. This fish is a relatively new addition to the fish keeping hobby. The Denison's barb is a schooling fish that is usually kept in groups of six or more.

Livebearers: colorful fish with a unique form of reproduction.

Livebearers have evolved a unique form of reproduction among fish: they give live birth instead of laying eggs. Fertilized internally, the embryos will take a month to develop before they can be safely released in the water by the mother. Miniature replicas of their parents, it will take up to two to three months for the newly hatched babies to reach adulthood. During this time they are extremely vulnerable to adult livebearers, includi

The Giant Gourami (Osphronemus goramy)

Originating from India it can grow up to 28" (70 cm). Giant gouramis can adapt to a wide range of water conditions from brackish water, to particularly slow-moving areas such as swamps, lakes and large rivers. Capable of breathing moist air, it can survive during dry seasons due to their ability to "climb" out of water and "walk" short distances in search of small ponds where they can remain for long periods, gulping up air at the surfa

Green Terror (Aequidens Rivulatus) Cichlid

The pair will breed in “open water” and usually spawn on a flat stone (remember this hint when aquascaping the tank). Water chemistry is of minor importance, however frequent water changes are a most to avoid hole in the head disease. Once a pair is formed they will easily spawn in […][...] Read more »
