Prionobrama: Greek, prion, -onos = saw + old French breme, bresme, a fresh water fish.
An unusual looking tetra with a completely transparent body and bright red fins which gives rise to the common name for these fish.
Wild glass bloodfins feed on insects worms and crustaceans but in captivity they readily accept a good quality flake food supplemented with suitably sized live or frozen food.
Males are smaller and more slender when adult. The anal fin of the male is longer than that of the female.
Breeding glass bloodfins is fairly easy since they are less fussy about water chemistry than most other characins and will even breed successfully in harder more alkaline water. Use a separate spawning tank with some fine leaved plants tied in bunches for a spawning mop. A well conditioned pair will normally breed within a few hours of being introduced to the spawning tank. The parents must be removed after spawning to prevent them from eating their own eggs. The eggs hatch after 24 - 36 hours and the fry will be free swimming about three days later. Once free swimming the fry can be fed on infusoria, a commercial liquid fry food (which incidentally encourages the growth on infusoria in the breeding tank) or hard boiled egg yolk in suspension. After a few days the fry should be large enough to accept newly hatched brine shrimps and micro worms and then powdered dry food.
The wild status of glass bloodfins has not been evaluated.
