Killifish Food Guide – Suitable Food for All Life Stages

Eating Habits of Killifish

The killifish usually do not eat pellet food. They are opportunistic feeders, consuming a wide variety of food sources. Their diet primarily consists of small invertebrates such as insects, worms, and crustaceans.

Foods for Newly-Hatched Killifish

The food should be ready before hatching the killifish eggs.

Live food in our shop

• Fairy shrimp (Newly-hatched)
• Rotifer

We recommend fairy shrimp. From our experience, the fairy shrimp is very easy to hatch. You should hatch 0.5/10 capsules of fairy shrimp eggs 1 day before hatching killifish eggs and use the dropper to transfer newly-hatched fairy shrimp to the killifish tray.

• Newly-hatched brine shrimp
• Microworms
