Distribution and habitat
The metal armored catfish are widely distributed from the north of South America (Trinidad and Tobago, Venezuela) to the La Plata Basin (Argentina). They live there in shallow, stagnant or slow-flowing waters with sandy, silty bottoms covered with dead wood, branches and leaves.
Maintenance
The aquarium should have dense planting with shady hiding places (roots). In order not to injure their barbels (serve for orientation and foraging), a soft, sandy substrate is ideal, which should be covered with some mulm and foliage (e.g. sea almond leaves).
No ammonia, ammonium and nitrite should be detectable, the nitrate value should not exceed 100 mg/l. To ensure the water quality and oxygen content, a filter and heater adapted to the aquarium size is required, as well as lighting for the species-appropriate day-night rhythm of the animals.
Diet
The food supply consists of live, frozen and dry food. For a balanced diet, feed once a day with a high-quality sinking dry food for catfish (granules, pellets, chips, tablets) as well as cyclops, daphnia, artemia, mysis, tubifex or mosquito larvae (live or frozen). In addition, occasionally some vegetable food, such as algae leaves or dry food with vegetable components (e.g. spirulina, kelp).
Only feed as much as is eaten within a few minutes. A regular and varied diet promotes health and increases resistance.
Behaviour and compatibility
They are peaceful and sociable fish that live in groups and can be kept well in a community tank with other peaceful fish. At least 5, but preferably more metal armored catfish should be kept together
Basically, only compatible fish species with similar water condition and water temperature requirements should be socialized.
Sex dimorphism
The sexes are difficult to distinguish. The females are slightly larger and more plump when seen from above.
Reproduction and breeding
A breeding group consists of 2-3 males and one female. During mating (T-position) the eggs enter a pocket formed by the ventral fins of the female and after fertilization they are glued to substrates (e.g. leaves, stems). This process is repeated a few times. The larvae hatch after about 2-3 days and swim freely after 2-5 days.
Young fish must be fed several times a day with special rearing food (infusoria). In a community tank breeding is hardly possible, because the spawn is easy prey.
Important
Corydoras aeneus are offered in some breeding varieties
They have additional intestinal respiration to survive in oxygen-poor waters and sometimes come to the water surface for air even in the oxygen-rich aquarium.
Foliage (sea almond, oak, etc.) enriches the water with humic substances, naturally lowers pH, and is a valuable secondary food source.
When fishing, use the finest mesh nets possible to avoid snagging the hard rays of the pectoral fins, which can cause painful puncture wounds when touched
The well-being of the fish should be checked regularly. Temperature should be checked daily, pH, hardness and nitrate levels at least every 14 days. Regular partial water changes are recommended, even when contaminant levels have not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced fish must be accustomed slowly to the water in the aquarium.
