The Blue Brazos crayfish is active and colorful. It’s easy to care for and doesn’t stress other tank mates. I’ve had it for three months and it’s thriving in my 10-gallon tank with tetras and corydoras. Water parameters are stable and the crayfish is always exploring the tank.

Great addition to my freshwater setup. It’s small and doesn’t dominate the tank. I noticed it eats algae and small bits of plant matter. Just make sure the tank has hiding spots and a stable environment.

The crayfish arrived healthy and active. It’s very curious and enjoys climbing rocks. I appreciate the clear instructions on water parameters. It’s a fun and low-maintenance pet for beginners.
