Which shrimp variants are specifically noted to become markedly more active after main lights go out?
Answer
Neocaridina or Caridina variants
The text specifically addresses the behavioral shift observed in common home aquarium crustaceans once the primary lighting source is extinguished. It points out that hobbyists frequently notice that small inhabitants, identified as being either Neocaridina or Caridina variants, display significantly increased activity levels following the transition to darkness. This observation confirms that these specific groups retain strong natural cues that dictate their active foraging and movement periods to the nighttime hours, even within the controlled setting of a glass tank.
