Petruichthys sp. rosy

- **Social Behavior**: Gregarious and tend to thrive in groups. It is advisable to keep them in small shoals of at least 6 individuals to observe their natural behaviors. - **Tank Setup**: A well-planted aquarium with plenty of hiding spots such as caves or driftwood is ideal. The substrate should be sandy to replicate their natural environment. - **Diet**: Omnivorous, accepting a varied diet of high-quality flake foods, sinking pellets, and live/frozen foods such as daphnia or bloodworms to maintain optimal health. - **Compatibility**: Best paired with other small, peaceful fish. They may become stressed or hide if housed with larger, more aggressive species.
