Knodus borki. Zarske, 2008. Common Name: Blue Tetra.
Classification
Characidae
Distribution
Colombia and Brazil.
Habitat:
Rivers, streams and tributaries.
Maximum Standard Length
2″ (5cm).
Aquarium:
Despite it’s diminutive size, this is a very active species and is not really suitable for tanks smaller than 30″ x 15″ x 12″ (75cm x 37.5cm x 30cm) – 88.5 litres.
Maintenance
Best kept in a heavily-planted arrangement with a dark substrate and floating plants to diffuse the lighting. If maintained in sparse surroundings it will not develop its best colours. Alternatively, it can look very effective in an Amazon-type biotope setup. Use sand as substrate and add some twisted beech branches and roots. Complete the effect by scattering a few handfuls of dried oak, beech or Indian almond leaves around the tank. You might also wish to add a net bag containing aquarium-safe peat or peat moss to the filter. This will release humic acids and tannins into the water, giving it a similar stained effect to the natural waters of the fish. The water should also contain plenty of dissolved oxygen.
Diet
Omnivorous and will accept most foods offered. It particularly relishes small live and frozen foods such as bloodworm, daphnia and brineshrimp. Some vegetable matter such as blanched spinach or a good quality Spirulina flake should also be included in the diet.
