A model-organism recommendation is not a care standard
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 genetics and husbandry boundary now includes the influential 2015 recommendation to develop Neocaridina as a functional-genomics model while identifying its care numbers and disease-resistance language as secondary synthesis, not new experimental evidence.
Why it changed
The seven-page policy paper arose from a symposium workshop, compared three candidate species and reported no new animals or systematic review method. It explicitly listed a complete genome and reliable gene-control methods as future work, while its pH, temperature, maturity, molt and egg statements came from selected older sources.
Sources reviewed for this change
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.
