Glass Bloodfin

The glass bloodfin has an almost completely transparent body; the spine and internal organs can be seen from outside. The base of the tail fin is red. In males, the leading edge of the anal fin is white with a dark line behind it, and the first rays are elongated. It is a hardy schooling fish that stays constantly on the move in the upper layer of the tank.

• At least 100 liters for a school of 8–12; a long tank should be preferred.
• 22–27°C, pH 6–7.5, soft to moderately hard water.
• Open swimming space in the upper layer and gentle to moderate flow.
• It can jump; a lid is required.

Omnivorous and mostly takes its food from the surface. Flakes, floating granules, frozen mosquito larvae, brine shrimp and daphnia are suitable. 1–2 meals a day are enough.

Peaceful and active; it swims as a school near the surface. It does not harm other species, but it outcompetes slow species at feeding time. It usually leaves adult shrimp alone but may eat their young.

Good companions: midwater tetras, rasboras, corydoras, plecos, peaceful dwarf cichlids.

Avoid: aggressive species that compete at the surface, large predators.
