A historical Neocaridina title can describe a Caridina population

The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.

What changed

The species, growth, breeding and temperature boundary now excludes the 1985 Lam Tsuen population paper from Neocaridina biological evidence while preserving its original title as a searchable historical record.

Why it changed

The paper was published as Neocaridina serrata, but the complete 1999 taxonomic revision examined Lam Tsuen material and reassigned the population to Caridina cantonensis. It also explained that neither C. cantonensis nor C. serrata belongs in Neocaridina. The older field correlations and inferred annual life history therefore cannot support N. davidi care or breeding calendars.

Affected practical guides

A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
