About Diminutus

Cambarellus diminutus. The smallest species in the genus. Adults max out around an inch. Native to the Gulf Coast of the southeastern US.

They're mostly translucent with brown or tan mottling. You can often see their internal organs through the carapace. Not flashy, but interesting to watch.

Same care as other Cambarellus. Their small size means they're even safer with shrimp and nano fish. Good for smaller tanks.
