It will be much easier to spot these little guys when they are in a small school. Also, due to their diminutive size, these small Corydoras will be less stressed with colleagues if there are larger fish swimming about.

Care Guide
Tank setup: A group of pygmy corys can live in a 10-gallon tank with a gentle, sponge-type filter, a heater, fine sand and plenty of plants. Change about 25% of the water every week. Corys are sensitive to salt and some medications (especially copper), so check labels before treating the tank.
Feeding: Feed tiny sinking pellets or crushed flake once or twice a day, plus small frozen or live foods like baby brine shrimp and daphnia. Make sure the food reaches them before faster fish eat it all.
Tankmates: Keep them with other tiny, gentle fish such as small rasboras, ember tetras, shrimp and bettas. Anything big enough to swallow them will.
Good to know: Unlike most corys, pygmy corys often swim in little schools in the middle of the tank, not just along the bottom.
