Care Guide

Diet

Striped Panchax are carnivorous surface hunters that require live or frozen foods as their primary diet, including mosquito larvae, brine shrimp, daphnia, and small insects. Feed small amounts once daily, offering only what they can consume in a few minutes. They may accept high-quality carnivore pellets but prefer live prey to stimulate natural hunting behavior.

Behavior

These are active, surface-dwelling killifish that spend most of their time near the water's surface hunting for prey. They are semi-aggressive and territorial, particularly males, which will chase and nip at smaller or slower-moving fish. They are excellent jumpers and require a secure, fitted lid to prevent escapes.

Breeding

Breeding in captivity is moderately difficult and requires separate breeding tanks with fine-leaved plants for egg deposition. Females scatter eggs among vegetation over several days, and parents should be removed to prevent egg consumption. Fry are tiny and require infusoria or liquid fry food before graduating to brine shrimp nauplii.
