Picture-style Gene Tree 12.0
What is known
The Cardinal shrimp controlled study reports 72.727% survival for pellet + Hydrilla, while an identified breeder reports approximately 20→300 Cardinal and 10→100 spinata animals. Their methods, times and denominators are not comparable.
What remains missing
No source here discloses a sequence of sexed mother and father breeding pairs, color-marker genotypes, controlled F1/F2 cohort censuses, or proven interspecies crosses. Dashed pedigree branches are therefore explicitly UNKNOWN.
Why a Lake Lindu shrimp is different
Herjayanto et al. studied C. kaili in cooler Lake Lindu inlet stream environments and documented survival after transportation. That is neither juvenile breeding output nor a model for warm Lake Matano Cardinal shrimp.

Published 2025 controlled C. dennerli food/shelter growout research — Survival 72.727% has no accessible study treatment numerator; no captive F1/F2 record, temperature trial or universal care thresholds.
- Peter Baert (Sulawesi Keepers, 2023), original first-person captive breeder log
Identified breeder reports approximate colony stock sizes, conditions and subsequent crash — Unmarked animals and no controlled experiment, no exact newborn count or DNA-verified parentage.

Original 2019 descriptive habitat, transport and short rearing survival paper, DOI 10.33512/jpk.v9i2.8629 — NOT a multigeneration breeding experiment; origin groups had different transfer journeys and no randomized control.
