|Buenos Aires tetra
|Hemigrammus caudovittatus (junior synonym)
|3" (7.5cm), but larger sometimes reported.
|South America: Argentina, Brazil and Paraguay.
|At least 3ft/92cm, with plenty of open swimming space. If live plants are used, they should be tougher varieties, as this
species will often eat softer-leaved plants.
|Normally peaceful, but may show some aggression towards smaller or more timid species. This is
less likely to occur when kept in a shoal of their own kind.
|Not critical, thrives in a range of conditions as long as extremes are avoided.
|Omnivorous: dry foods such as flake and granular foods supplemented with live/frozen foods, and a vegetable component.
|Males slimmer, often with more vivid colours.
|A fairly easy fish to breed. Use a temperature in the middle to upper end of
the range quoted above. Spawning takes place over plants and the eggs hatch in about a day.
This is a hardy fish which will tolerate a range of conditions and is hence often recommended for beginners.
A tank partially planted with hardy plants is recommended, as they may nibble more delicate plants. This is an
active shoaling species which grows a little larger than many tetras, and therefore requires a little more swimming
space. A colour variant exists in which the caudal fin is lemon-yellow.
