Panda Garra

Geographic Origin and Biotope: Endemic to western Myanmar (Burma), in the waterways of the Arakan Mountains. It is a typical inhabitant of cool, highly oxygenated mountain streams with bottoms of stones, pebbles, and gravel on which a thick film of sun-exposed algal biofilm grows.

Taxonomy and Morphology: Cyprinid adapted to fast bottoms (rheophilic). Club-shaped morphology, lacking a functional swim bladder to sink effortlessly in rapids. The ventral sucker mouth is modified into a disc shape to adhere tenaciously to rocks under extreme currents while scraping biofilm. Reaches 8-9 cm (3.5 inches).

Social Behavior: Highly gregarious and extremely peaceful, but with complex intraspecific hierarchical interactions. They often stage "power dances" side-by-side, pushing each other and fading their colors, without injury. Absolutely must be kept in a school of at least 5-6 specimens; keeping it alone induces depression and fatal apathy.

Coloration and Sexual Dimorphism: The livery is exquisite and unusual for scraping species: dark chocolate-brown body with massive bright yellow/golden vertical bands (hence the name Panda). Fins have red hues. In mature females, the belly is distinctly swollen, while dominant males develop prominent breeding tubercles (horny spikes) on the snout and head.

Aquarium Setup: The aquarium must replicate a stream (Hillstream). Use a powerful filter or wavemakers generating a torrential water flow from one side of the tank to the other. Decor based on piles of large, smooth, polished river pebbles. Plants are not present in their core biotope, but Anubias and Ferns attached to wood are well tolerated.

Diet and Feeding: Primary consumer of biofilm and aufwuchs, but unlike other algae eaters, it has a strong omnivorous tendency. Provide sinking vegetable tablets (Spirulina), zucchini and cucumber slices, supplemented twice a week with frozen bloodworms and brine shrimp, which it consumes voraciously by scraping them from the bottom.

Water Quality: Requires pure, pristine, and hyper-oxygenated waters. Temperatures of 22.0-27.0 °C (72-80 °F). Neutral pH (6.5-7.5) and medium hardness (GH 2.0-12.0). Water quality is vital: organic pollutants, nitrates above 20mg/l, and stagnant water depress the immune system leading to fatal bacterial skin infections.

Compatibility and Tankmates: Perfect creature for rheophilic community aquariums ("Hillstream tanks"). Excellent companions are Balitorids (Sewellia, Gastromyzon), fast Danios, Rasboras, and peaceful Corydoras. Completely ignores other fish. Do not insert with large, aggressive territorial bottom-dwelling Cichlids.

Aquarium Reproduction: Very rare and difficult, but possible provided females are conditioned with massive doses of live food and a drastic change of fresh oxygenated water, simulating the onset of the Burmese monsoon season. They scatter free eggs among the pebbles at dawn. Breeders must then be removed to prevent cannibalism.

Risks and Diseases: Highly sensitive to bacterial diseases like Flexibacter columnaris if placed in immature aquariums or with poor substrate hygiene. The major cause of death among novices is oxygen deprivation and chronic starvation induced by the myth that it "only eats algae, cleaning the glass".
