The Angular Dwarf Crayfish, scientifically known as Cambarellus lesliei, is a fascinating little crustacean that calls the waters of Alabama and Mississippi home. This pint-sized crayfish belongs to the Cambaridae family, which includes many of its crayfish cousins. What makes this critter so special? Well, for starters, it’s one of the smallest crayfish species around, barely growing larger than your thumb!

These tiny creatures have a knack for hiding in submerged plants in slow-moving or still waters. They’re bottom-dwellers, scurrying along the riverbed in search of tasty morsels. Like many crayfish, they’re not picky eaters and will munch on just about anything they can find, from plant matter to small insects and even leftover fish food.
The name Cambarellus lesliei might sound fancy, but it’s pretty straightforward. Cambarellus means “little crayfish” in Latin, while lesliei is likely named after a person, possibly the scientist who first discovered or described the species.
In the aquarium trade, you might hear these little guys called “Angular Dwarf Crawfish” or simply “Dwarf Crayfish”. They’re not as common in pet stores as their Mexican cousins, but they’re just as charming.
One cool thing about these crayfish is their molting process. Like all crustaceans, they have to shed their exoskeleton to grow. During this time, they’re completely defenseless and will hide until their new shell hardens. It’s like they’re getting a whole new suit of armor!
While there isn’t a ton of scientific research specifically on C. lesliei, studies on related species have shown that these little crayfish can be quite hardy. They can tolerate a range of water conditions, making them adaptable to different environments.
Interestingly, the Angular Dwarf Crayfish is listed as vulnerable by NatureServe. This is because they have a limited range and face threats from pollution and habitat disturbance in their native waters. It’s a reminder of how important it is to protect our waterways and the unique creatures that call them home.
So next time you’re near a slow-moving stream in Alabama or Mississippi, keep an eye out for these tiny, fascinating crustaceans. They might be small, but they play a big role in their aquatic ecosystem!

FAQs about Angular Dwarf Crayfish
How often do Angular Dwarf Crayfish molt?
Angular Dwarf Crayfish typically molt every 3-4 weeks when they’re young and growing rapidly. As they mature, the frequency decreases to about once every 1-2 months. The molting process is crucial for their growth and regeneration of lost limbs.
Can Angular Dwarf Crayfish live in a planted aquarium?
Yes, these crayfish can thrive in planted aquariums. They generally don’t damage healthy plants and may even help keep the tank clean by eating algae and detritus. However, they might occasionally nibble on delicate plants, so it’s best to provide them with hardy plant species.
Do Angular Dwarf Crayfish need a filter in their tank?
While these crayfish are relatively hardy, a filter is still recommended to maintain good water quality. A small sponge filter or low-flow HOB filter is suitable for their tank. Ensure the filter intake is covered to prevent the crayfish from getting stuck.
How many Angular Dwarf Crayfish can I keep in a 10-gallon tank?
A 10-gallon tank can comfortably house 3-5 Angular Dwarf Crayfish. However, it’s important to provide plenty of hiding spots and territory for each crayfish to reduce potential conflicts.
Will Angular Dwarf Crayfish eat fish eggs?
If given the opportunity, Angular Dwarf Crayfish may eat fish eggs they come across. If you’re planning to breed fish in the same tank, it’s best to separate the crayfish or provide ample protection for the eggs.
How can I tell if my Angular Dwarf Crayfish is stressed?
Signs of stress in these crayfish include hiding more than usual, loss of appetite, aggressive behavior, or attempting to climb out of the tank. Rapid movement of their swimmerets (small appendages under the tail) can also indicate stress.
Do Angular Dwarf Crayfish need special lighting?
These crayfish don’t have specific lighting requirements. However, a standard aquarium light on a regular day/night cycle can help maintain their natural behavior patterns and benefit any live plants in the tank.
Can Angular Dwarf Crayfish live in brackish water?
No, Angular Dwarf Crayfish are freshwater species and cannot tolerate brackish conditions. They should be kept in freshwater aquariums only.
How do I acclimate Angular Dwarf Crayfish to a new tank?
Acclimate them slowly by floating their transport bag in the new tank for about 15 minutes to equalize temperature. Then, gradually add small amounts of tank water to their bag over the course of an hour before gently releasing them into the tank.
What should I do if my Angular Dwarf Crayfish loses a claw?
Don’t worry if your crayfish loses a claw. They can regenerate lost limbs over time through the molting process. Ensure good water quality and proper nutrition to support their regeneration.
