Results for “general hardness”

Little sun is able to penetrate the forest floor so aquatic habitats are shaded and water temperature may be relatively cool, while conductivity and hardness are generally low and pH slightly acid. Macrophytes are uncommon though there may be dense, marginal vegetation, sometimes overhanging the full width of the stream, the roots of which may penetrate the banks underwater. Typical substrates are sandy but covered by a layer of leaf litter with fallen twigs and branches.

Generally considered one of the hardiest small cyprinids available in the aquarium hobby, P. conchonius is an excellent choice for the beginner. Selective breeding has produced various ornamental strains including long-finned, 'veil-tail', 'super red', 'neon', and 'golden' forms. It's also been hybridised with some congeners although the offspring of such experiments are apparently infertile. It was formerly included in th...

This species is also known as 'Daget's panchax', 'black-lipped panchax', 'orange-throated panchax' or 'firemouth killifish' and is an aquarium stalwart with the red-throated form having first been exported in 1908. It's an excellent choice for those new to killifishes or egg-laying species in general since the aquarium strain is well-established, quite hardy and easy to breed. There was some initial confusion after Belgian ich...

Nannacara Anomala are widely available in the trade, and are generally regarded as an excellent beginner's fish. If a beginner is interested in keeping Cichlids and learning about breeding, then these fish are absolutely ideal. Anomala are attractive, hardy and usually quite cheap to purchase. Like some species of the Apistogramma genus, the mother may use fascinating body language to communicate with her fry when she is caring for them. If there is more than one male in a tank smalle...

This species is not actually a piranha in ichthyologic terms, being monotypic and therefore unique. It was so named due to its general resemblance to true piranha, and the fact that it is quite closely related to Pygocentrus species. Mento means "chin", referring to the protruding jaw of the fish. This jaw structure, along with the adapted teeth, is used in its natural feeding behaviour. It has been observed to swim at great speed into a selected target, biting hard as it collides w...
