Frequently asked questions

About Elephant Fish (Pollimyrus isidori).

How do I care for Elephant Fish?

Provide an aquarium at least 100 cm long with dense live planting so they have shaded retreats. Maintain soft to moderately hard water between 22–30°C with a pH of 6.0–8.5. Their diet is straightforward—feed live or frozen foods such as bloodworms, though they usually accept sinking pellets once settled. Crucially, never keep them with shrimp, which will end up as snacks.
