Red Bee shrimp digestive-enzyme evidence
A laboratory study of Red Bee shrimp reported as Caridina cantonensis measured protease, amylase, lipase, cellulase, trypsin and chymotrypsin activity in 15- and 60-day-old shrimp across pH 2–12. Protease activity was strongest under alkaline conditions (reported optimum pH 8–10, highest at pH 10), and alkaline amylase activity exceeded acidic amylase activity in both age groups. The study also evaluated in-vitro digestibility of feed raw materials using shrimp digestive enzy
Claim class: EVIDENCE-BACKED / DIGESTIVE-PHYSIOLOGY, STUDY-SPECIFIC. This supports evidence that Red Bee shrimp possess multiple digestive-enzyme pathways and that digestive performance varies with pH. It does not establish a universal aquarium-water pH target, a complete diet, an optimal protein percentage, a feeding frequency, or a superior commercial brand.
Wild Caridina food-use evidence
Stable-isotope research on wild Caridina cantonensis and C. serrata in Hong Kong streams evaluated leaf litter, fine particulate organic matter (FPOM), and periphyton as potential food sources across shaded/unshaded streams, seasons, developmental stages and sexes. The work establishes these shrimp as omnivorous stream consumers whose resource use is linked to naturally available benthic/detrital material rather than supporting a single-feed model.
Claim class: EVIDENCE-BACKED / WILD TROPHIC ECOLOGY. Apply this as natural-diet context only; do not silently transfer wild Hong Kong stream resource proportions into Taiwan Bee aquarium ration percentages.
