Glass Bloodfin Tetra

The Glass Bloodfin Tetra is a lesser-known tetra species and whilst simple in its colours, it is a stunning fish in its regard. These fish make for a great low-key addition to a planted aqua scape where the environment is the spotlight. Alternatively, they are also a great species for a wild-style biotope tank due to their more natural colour palette. What sets the Glass Bloodfin apart from other tetras is its almost completely transparent body.

Glass bloodfin tetras fit their name perfectly. They have an almost fully see-through body with the spine being perfectly visible, there is just a slight olive-green tinge which is just their scale colour. The scales also have a criss-cross pattern from head to tail with the only break here being the belly region which is a pure platinum colour. The blood fin part of the name comes from that bright red tail fin, on the topic of fins, almost all the other fins on this species trail like a long fin strain.

Glass bloodfin tetras are egg scatterers and relatively easy to breed. After a courtship dance, the female scatters her eggs among fine-leaved plants, which are then fertilized by the male. There is no parental care provided, and removing the adults after spawning is advised to prevent egg predation. The male boasts a slenderer body compared to the female and also has longer fins. The best method of success in breeding would be to put a single male with a pair of females into a 40-liter aquarium with a spawning mop or java moss. After spawning the parents can be taken out and the fry can be raised.

Tank Recommendations for your Glass Bloodfin Tetra

Glass bloodfin tetras are best housed in a densely planted 70-litre or larger tank with plenty of swimming space. Since these are mid-water fish they are not fussed with the hardscape or substrate choices in an aquarium. A blackwater, hardscape only, or even planted aquarium will be fine however they would stand out best in the latter option, especially against the greens. They prefer soft, slightly acidic water with temperatures between 24 - 28°C and a pH of 5.5 - 7.0. Providing a darker background and substrate can help intensify their colours as well.
