Bright, bold, and unmistakable.
Rubber Ducky isopods (Cubaris sp.) come from Thailand and carry a warm yellow face that gives the species its playful name. They are a favorite among keepers who want a display species with real personality. This is a moisture-loving species that wants things kept consistently damp with plenty of calcium on offer. In a well-built bioactive setup at 72 to 80F and 75 to 90% humidity, a small starter group can grow into an eye-catching colony over time.
- Distinct yellow-faced coloration
- A true showpiece for a tropical bioactive enclosure
- Thrives with consistent moisture and calcium supplementation
- A rewarding project for keepers ready to step up from beginner species
