Lit-dish counts do not establish the best shrimp light
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 habitat and behaviour guides now include an open two-trial Neocaridina light-spectrum thesis while separating its location counts from preference, welfare and long-term lighting advice.
Why it changed
The rotating-lamp trial strengthens the colour-associated signal, but irradiance was not measured or equalized, illumination stayed on the left, the repeated-count model was incompletely specified and coloured lamps could change observer detection of red shrimp. The first trial confounded colour with aquarium, and the stated light period does not overlap the observation hours. No stress, growth, survival comparison or reproductive-rate endpoint was measured.

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.
