Taxon and evidence category
C. dennerli and C. spinata — loss severity in keeper diary
Illustrated breeder-to-observation evidence tree
Original dated study or breeder account
August 2022 experience after earlier colony growth
Actually reported measurements
Approx. 90% loss in two tanks; breeder hypothesized accumulated detritus
Evidence interpretation
Negative longitudinal breeding outcome
Why this is NOT an inheritance ratio
Detritus hypothesis not causally tested; co-present ostracods/worms cannot identify cause Parent sexes, specimen IDs, and F1/F2 genotype-phenotype cohorts not disclosed
Conservation and care boundaries
Do not collect threatened wild populations; require documented captive-bred stock and stable measured conditions, avoid aquarium releases.
