Extreme Blue Bolt Shrimp (Caridina spinata 'Extreme Blue Bolt')

The Extreme Blue Bolt is a premium selectively bred variant of Caridina spinata, developed by specialist Taiwan and Asian breeders to produce an exceptionally vivid, fully saturated blue coloration that surpasses standard Blue Bolt shrimp in intensity and coverage. Its deep, jewel-like blue body with white markings places it among the most visually striking freshwater invertebrates available anywhere in the hobby. Like all Taiwan Bee Caridina, it demands pristine, tightly controlled water parameters — soft, acidic water with very low mineral content and near-zero alkalinity. Recommended exclusively for dedicated, experienced shrimp keepers with an established, specialized Caridina setup using active substrate (aquasoil) and RO water remineralized for Caridina.

Maintain in a dedicated Caridina shrimp tank with active substrate (ADA Amazonia, Benibachi, or equivalent) and RO water remineralized with Caridina-specific mineral additives. Target parameters: pH 5.8–6.5, GH 3–6, KH 0–2, TDS 100–150 ppm, temperature 20–24°C. Avoid tap water unless properly treated. Feed lightly with specialized shrimp foods, biofilm wafers, and leaf litter. No fish tank mates — keep in species-only or other Caridina shrimp groups. Extremely sensitive to ammonia and nitrite; only introduce to a fully cycled tank.
