Overview

October 16, 2026 · Suggest an edit

The European weatherfish is the European relative of the Asian dojo. It grows larger (20–25 cm) and is distinguished by dark stripes running the length of its yellowish-brown body. Because it can breathe air through its gut, it can live in muddy, oxygen-poor waters. As its natural habitats have declined, it is listed in the Bern Convention and is protected in some European countries; it should only be obtained from legal captive-bred sources and must never be released into the wild.

Tank Setup

October 16, 2026 · Suggest an edit
  • At least 250 liters and 120 cm of length for 3–5 adults.
  • 12–20°C; no heater is needed, but overheating must be prevented in summer.
  • Fine sand or a soft substrate; it often buries itself. Roots and sturdy plants.
  • A tight lid is essential; it jumps, especially at night.

Diet

It feeds on insect larvae, worms and small crustaceans on the bottom. Alongside sinking granules and tablets, offer bloodworms, tubifex and small worms. It eats shrimp that fit in its mouth.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

Peaceful toward other fish; it is more active at night and when air pressure changes. During the day it mostly waits buried.

Good companions: peaceful fish that like cold water: White Cloud Mountain minnows, coldwater barbs, other coldwater species of the same size.

Avoid: shrimp, very small fish and fry, species that need tropical temperatures.
