Gamba Arlequín: Caridina wolterecki de los lagos antiguos de Sulawesi, blanca porcelana con bandas pardorojizas. Requiere agua cálida dura alcalina a 26-30 °C (pH 7,5-8,5) — especie para especialistas.
Harlequin Shrimp is the strikingly patterned Caridina wolterecki from the ancient lakes of Sulawesi, Indonesia — Lake Poso and the Malili lake system — where it clings to rocks in warm, hard, alkaline water that would kill the soft-water bee shrimp. Its body is porcelain white broken by irregular reddish-brown bands and blotches, a harlequin pattern no other popular shrimp matches. It is a specialist in every sense: 26-30 °C, pH 7.5-8.5 and 7-12 dGH, strong light encouraging the algae it grazes, and excellent oxygenation. In the aquarium it needs a dedicated Sulawesi setup — often escarpment-style rock aquascapes with very clean, well-filtered water — and accepts algae, biofilm and spirulina-based foods. It grows to 2-3 cm, is shy at first but becomes bold in stable conditions, and breeds in freshwater, females carrying 10-20 relatively large eggs. Sensitive to nitrate and to sudden changes, it rewards the specialist with one of the most beautiful patterns in the hobby. Never mix its hard alkaline regime with soft-water caridinas.
Solo para expertos. Very peaceful; Groups of 10 or more.
26–29 °C con estabilidad; pH 7.5–8.5, GH 6–12 dGH.
De adulto mide 2–2.5 cm. Vive bottom — grazing rock and sponge surfaces, así que 30 L o más.
Algae and aufwuchs grazer; spirulina foods. Combina pienso con alimentos congelados o vivos.
Very peaceful; Groups of 10 or more. Buenos compañeros: Other Sulawesi lake shrimp — Shared hard alkaline chemistry — the only safe mix, Sulawesi snails (Tylomelania) — Same lake system, same parameters.No convive con Soft-water Caridina (bee shrimp lines) — Opposite chemistry; one side dies, Copper-based medications — Lethal to all invertebrates, Any nitrate-prone setup — Sulawesi shrimp demand near-zero nitrate.
Originario de Lake Towuti, Sulawesi, Indonesia — endemic; vive en deep, hot, alkaline crater lake with rocky shores. Gentle current; high oxygen.
En acuario: breeds in freshwater. The female carries 10-20 relatively large eggs for about four weeks; hatchlings are well-developed. Success depends on rock-solid parameters and clean water rather than any trick.. Females are larger and deeper with broader banding; males slimmer with finer lines..
