Tiny River Scouts: Caring for Miniature Armored Catfish
If you have ever watched a group of tiny, whiskered fish scooting along the bottom of an aquarium like a coordinated search team, you have probably met dwarf corydoras or other small armored catfish. These fish are sometimes called mini catfish or micro corys, and they are beloved for their playful behavior, peaceful nature, and endearing appearance. Understanding how to care for them properly is the key to keeping them healthy, active, and full of personality.
The first thing to know about these little river scouts is that they are highly social. In nature, they live in large groups, sifting through sand and leaf litter together. In a home aquarium, they should never be kept alone. A group of at least six of the same species is recommended, and more is often better if the tank size allows. When they feel safe in a group, they show more natural behaviors, explore the tank together, and experience less stress.
Tank layout and substrate make a big difference to their comfort. These fish spend much of their time on the bottom, using their sensitive whiskers, called barbels, to search for food. A soft, smooth substrate is essential. Fine sand is ideal because it lets them dig and forage without damaging their barbels. Rough gravel or sharp stones can injure them over time, leading to infections or difficulty eating. Adding smooth rocks, driftwood, and live plants gives them hiding places and breaks up sight lines, making them feel more secure.
Water quality is another critical part of their care. Mini armored catfish generally prefer clean, well oxygenated water with stable parameters. Many species do well in slightly acidic to neutral water, but consistency is more important than chasing perfect numbers. Regular water changes, gentle filtration, and avoiding sudden swings in temperature or chemistry help keep them healthy. Because they are small and sensitive, they should never be placed in an uncycled or unstable tank.
One of the most charming behaviors you may notice is their habit of darting to the surface for a quick gulp of air. These fish possess a modified intestine that allows them to absorb oxygen from air as a backup to gill breathing. Occasional surface trips are normal, but if they are gasping constantly, it can signal poor water quality or low oxygen levels.
Feeding these bottom dwellers correctly means more than just sprinkling flakes at the surface. While they may snack on leftovers, they need their own sinking foods to thrive. Small sinking pellets, wafers, and frozen or live foods like bloodworms or daphnia work well. Offering a variety of foods and feeding after lights dim can ensure shy individuals get their share. Overfeeding should be avoided, as uneaten food can quickly foul the water.
Choosing peaceful tankmates is also important. Tiny armored catfish do best with small, calm fish that will not nip at their fins or outcompete them for food. Avoid large or aggressive species. When kept in the right group size, in a soft bottomed, well planted tank with clean water and gentle companions, these miniature armored explorers reward you with constant motion, curious behavior, and a glimpse into the hidden life along the riverbed.
