Why crab compatibility matters
Freshwater crab species differ in size and behavior; many require care conditions that are not the same as a Neocaridina tank. In a shrimp-focused aquarium, the choice should also support steady routines, visible livestock, and access for basic care.
Before you act, check species, adult size, feeding style, and the crab's ability to reach shrimp. Compare the item with the rest of the setup and note any recent change that could affect what you are seeing.
A careful way to proceed
consult a species-specific guide and choose separate housing if uncertainty remains. Make one adjustment at a time and watch how the aquarium responds during normal observation.
Avoid assuming a small juvenile crab will stay small or ignore shrimp. Labels, products, and tank conditions differ, so use a reliable guide as context and record what you directly observe. If uncertainty remains, ask an experienced shrimp keeper before making a consequential change.
