The Kwikkwi Catfish (Hoplosternum Thoracatum) is a substantial armored catfish that grows significantly larger than the more familiar Corydoras species, reaching up to 18 cm in length. Unique feature: this catfish builds a bubble nest at the water surface to protect its eggs — quite unusual behavior for an armored catfish.

✂️ Care

Keep as a pair or harem in a spacious aquarium of at least 120 cm — due to its size, this catfish requires plenty of space. Provide floating plants or decoration at the water surface; here, the fish will build its bubble nest to protect the eggs. Choose a soft, non-sharp substrate like sand to protect its delicate barbels.

🐠 Combination tip

Relatively peaceful, but due to its size, best combined with other medium-sized, not overly shy community fish.
