Hoplo Catfish Breeding

Breeding Hoplo Catfish can be a rewarding experience, allowing you to raise your own community of these intriguing fish. While breeding these catfish may not be as straightforward as other species, it is certainly achievable. Let’s explore the steps and conditions necessary for a successful breeding process.


Sexing Hoplo Catfish can be challenging due to the subtle differences between males and females. Mature males tend to be slightly slimmer and smaller than females, while females possess a fuller and rounder body, especially when carrying eggs.

Breeding Tank Setup

A separate breeding tank is recommended for Hoplo Catfish breeding. This tank should be equipped with:

  • Soft sand or fine gravel substrate
  • Heater maintaining a temperature of 77-82°F (25-28°C)
  • Quiet sponge filter
  • Plenty of hiding spots, such as caves or PVC pipes
  • A spawning mop or fine-leaved plants


To encourage spawning, follow these tips:

  • Increase the water temperature gradually to the higher end of their preferred range (around 82°F or 28°C)
  • Condition the breeding pair with a varied diet, including live and frozen foods
  • Perform more frequent water changes to simulate rain and trigger their breeding instincts

Egg Laying and Fertilization

When the female is ready to lay her eggs, she will search for a suitable hiding place, such as a cave. The male will follow her, and they will lay side-by-side as the female deposits her eggs. The male will then fertilize the eggs, which will typically adhere to surfaces like caves or plants.

Post-Spawning Care

Once spawning has occurred, it’s essential to remove the adult fish, as they might consume the eggs. Keep the breeding tank temperature stable, and make sure the sponge filter provides gentle water circulation without any strong currents.

Fry Care

Hoplo Catfish eggs will usually hatch within 3-5 days, and the fry will be free-swimming after another 2-3 days. Newly hatched fry can be fed infusoria or liquid fry food for the first few days, then moved onto newly hatched brine shrimp and microworms as they grow larger. Gradually transition the fry to larger foods until they can consume standard Hoplo Catfish fare.

With proper care, patience, and attention to detail, breeding Hoplo Catfish can be a rewarding and fascinating experience for any aquarium enthusiast.


Hoplo Catfish are captivating and hardy aquatic pets that make an excellent choice for beginner fishkeepers. By following this comprehensive guide, you’ll be equipped with the essential knowledge and practical tips needed to care for your Hoplo Catfish effectively.
