Characins – Tetras 01/02/2001
Genera: Cheirodon, Hemigrammus, Hyphessobrycon, Paracheirodon, Pristella.
Geographic Origin: South America. Very widespread throughout.
Common Names: Cardinal Tetra, Neon Tetra, Serpae Tetra, Lemon Tetra etc.
Compatibility: Generally speaking, these fish are very compatible with one
another. One exception is possibly the Brass or Yellow Tetra –
Hyphessobrycon bifasciatus. This fish can be a 'fin nipper'.
Minimum Aquarium Size: As they are mainly fish that grow to less than 50mm
(2”), they can be safely kept in a 600mm x 300mm
x 300mm (24” x 12” x 12”) inch aquarium.
Larger aquariums however, are always preferable.
Temperature: Generally between 24o28oC 75o/82oF , although many will be
quite happy at lower temperatures.
Habitat:These fish really show their best colours in a well planted aquarium,
perhaps furnished with bogwood and a dark substrate.
Water movement provided by a power filter is ideal.
Water Parameters: These fish come from areas where the water is soft and
acid and will always do best under these conditions.
Most Tetras however will readily adapt to hard alkaline
water though not for breeding purposes. Water should be
clean and clear. Fish will benefit from a 25% water
Health: Not generally noted for having health problems.
Diet: Will readily accept all forms of dried, frozen and live foods.
Plants: Not plant eaters. All species of tropical plant are acceptable in the
Breeding Notes : Egg-scatterers. Use dense bunches of fine-leaved plants, or
nylon mops, as egg receptacles when spawning.
Fertilised eggs may be adversely affected by wrong water
conditions and/or exposure to light.
Availability: Probably the most available of all tropical fish. Only select fish
that are alert and swimming with fins erect. Inspect closely for
signs of disease. Reject lethargic, damaged or hollow-bellied
Show Class: FBAS Show Class Ca or C.
