Frequently Asked Questions
-
Corydoras are omnivores. Feed them sinking pellets, wafers, frozen bloodworms, brine shrimp, and blanched vegetables. Avoid relying solely on them to "clean up" leftover food.
-
A minimum of 6 is recommended — they're schooling fish and thrive in groups. Larger groups of 10 or more show more natural behavior and reduce stress.
-
A 20-gallon long is the minimum for a small group. Longer tanks are preferred over tall ones since corydoras are bottom dwellers.
-
Temperature: 72–78°F, pH: 6.0–7.5, Hardness: 2–12 dGH. They prefer soft, slightly acidic water similar to South American rivers.
-
Yes — fine sand or smooth gravel is essential. Sharp substrate can damage their sensitive barbels, leading to infections.
-
They're peaceful and work well with tetras, rasboras, livebearers, and dwarf cichlids. Avoid aggressive or fin-nipping species.
-
They gulp air at the surface to supplement oxygen through their intestine — this is normal. However, frequent surfacing can signal poor water quality.
-
Trigger spawning with a water change using slightly cooler water. They lay eggs on glass or plants. Remove eggs to a separate tank to prevent predation.
-
Otocinclus, kuhli loaches, and nerite snails are great tankmates. Avoid large plecos that may compete aggressively for territory.
-
They prefer moderate flow that mimics their natural habitat. Strong currents can stress them — use a sponge filter or baffle your HOB filter output.
