Using photosynthetic bacteria (PSB) as a food source for fish fry offers several advantages:

1. **Nutrient-Rich Diet**: PSB provide essential nutrients, including proteins, amino acids, and vitamins, which are crucial for the growth and development of fish fry.

2. **Enhanced Digestibility**: The presence of PSB can improve the gut microbiota of fish fry, leading to better digestion and nutrient absorption.

3. **Boosted Immune System**: PSB produce bioactive compounds that enhance the immune response, helping fish fry resist diseases.

4. **Improved Survival Rates**: With better nutrition and a stronger immune system, fish fry have higher survival rates.

5. **Cleaner Environment**: PSB can help maintain water quality by breaking down organic waste, reducing harmful substances, and preventing pathogen growth.

Incorporating PSB into the diet of fish fry supports healthier, faster-growing, and more resilient young fish.

Two sizes are available, both packaged in a transparent pouch. The bacteria love sunlight, so you can leave them outside in full sunlight.

Full disclaimer: Photosynthetic bacteria (PSB) can produce a bad smell, often resembling rotten eggs, due to the production of sulfur compounds, particularly hydrogen sulfide (H₂S).
