Does a direct feeding study establish one complete diet, live feed, ration or nutrient target for a Neocaridina colony?
This record shows how a current Neocaridina evidence gap was searched. It supports a dated statement about this search, not proof that no unlocated study exists.

Candidate-source decisions
The effectiveness of natural feed in enhancing color and survival rate of ornamental shrimp Neocaridina sp.
The complete PDF supports a three-aquarium-per-feed, 40-day comparison, but unidentified genus-only stock, unmeasured ad-libitum intake, unresolved starting counts, conflicting colour scales and statistical text prevent a universal Tubifex or live-feed recommendation.
Effects of different aquarium feeds on growth performance and survival rate of red cherry shrimp Neocaridina denticulata
Four branded products produced different growth and survival patterns, but formulation and physical form changed together and feeding to satiation does not establish a ration or isolate Spirulina.
Effect of commercial diets on female reproductive performance and offspring quality in the red cherry shrimp Neocaridina davidi
Three commercial diets support bounded broodstock and offspring comparisons, but their particular formulations do not define a complete diet for every life stage or current product.
Effects of dietary incorporation of Arthrospira platensis meal on growth, survival, body composition, and reproductive performance over successive spawnings
The long formulated-diet trial measures multiple life-cycle outcomes, but Arthrospira replaced fish meal and the percentages are treatment formulations rather than a universal additive or food requirement.
Growth, reproduction and pigmentation performances of red cherry shrimp Neocaridina davidi fed with black soldier fly larvae Hermetia illucens meal
Five complete formulas varied several ingredients together and retained unclear intake, water and analysis units, so the result cannot define a whole-insect ration or universal replacement level.
Search outcome
Direct feeding studies show that diet treatment can change growth, survival, colour and reproductive endpoints, but no reviewed source defines one complete food, live-feed requirement, pellet count or nutrient target across the full colony life cycle. The adequacy gap remains open.
