Aquarium Breeding Logs & Catfish Caves

Choosing a Breeding Log

Research the spawning behaviour of the exact species and measure the adult fish. The cave should provide a suitable entrance and internal space without trapping the fish.

• Match the cave to the adult fish’s size.
• Check the number and shape of openings.
• Choose an aquarium-safe, cleanable material.
• Place the log securely so it cannot roll.

Bristlenose Breeding Caves

Male bristlenose catfish commonly guard eggs in an enclosed cavity. The cave should allow entry and fanning while remaining appropriately confined for the pair.

Caves for Other Fish

Some cichlids and other fish use caves, but preferences differ by species. A product labelled as a breeding cave is not automatically suitable for every cave spawner.

Position and Privacy

A stable position with appropriate cover may help fish settle. Keep the entrance observable enough for safe checks without repeatedly disturbing the breeding fish.

Preparing the Aquarium for Breeding

Cycle and stabilise the aquarium before breeding. Provide species-appropriate filtration, diet, hiding places and water conditions.

Inspect the cave between uses and clean it with aquarium-safe methods. Do not use household detergents.
