Corydoras adolfoi is a small catfish prized for its striking three-tone pattern: a white body, a black mask across the eyes, a dark diagonal band across the back, and an orange patch behind the head. Native to the Rio Negro basin, it has a calm, peaceful temperament that makes it a good tankmate for many other fish. Watching it forage along the substrate with its barbels is one of its charms, and because it's a naturally shoaling species, keeping several together lets you see its calmer, more natural behavior. It prefers soft, slightly acidic water, so water quality needs a bit of extra attention — this is generally considered a fish for hobbyists with some Corydoras experience. It's also known for its close resemblance to the closely related Corydoras duplicareus.

- Sinking dried foods, frozen bloodworm, Tubifex
- Tank
- Use fine rounded sand with wood and leaf litter for cover, and never block access to the water surface.
- Water Temperature & Quality
- 20-26C, pH 4.0-7.0, 1-5dGH; soft, acidic water is preferred. FishBase records 22-26C, pH 6.0-8.0 and 2-25dH in the wild.
- Tank Mates
- Peaceful and gregarious; keep at least four to six. Pair it with fishes of similar water requirements, such as soft-water characins.
- Diet & Feeding
- A foraging omnivore. Offer sinking dried food plus frozen bloodworm and Tubifex. It must never be expected to live on leftovers or to clean the tank.
- Breeding & Spawning
- Use two males per female. Once females are gravid, make a 50-70 percent water change with cooler water and raise oxygenation and flow. Eggs are laid on glass, fine-leaved plants or spawning mops.
- Health & Notes
- Assessed Least Concern by the IUCN Red List. It closely resembles Hoplisoma duplicareum, so a shop label alone may not identify which species you have.

7 things to know before welcoming a Adolfo's Corydoras
1Prefers Soft, Acidic Water
Corydoras adolfoi comes from the Rio Negro basin and prefers soft water on the acidic side. Prepare the water chemistry before introducing them and avoid sudden changes.
2Calmer in a Shoal
This species naturally shoals, so keeping several together helps them settle in and show more natural, confident behavior than a single fish would.
3Choose Substrate Carefully

4Look-Alike: C. duplicareus
This species closely resembles the related Corydoras duplicareus. Check the pattern details and confirm the labeled species before buying.
5Sensitive to Sudden Changes
They can be sensitive to abrupt shifts in water parameters, so do small, frequent water changes and match temperature and chemistry closely.
6Peaceful, Community-Friendly
Adolfoi corys are peaceful and rarely bother other fish, making them good tankmates for similarly water-loving species. Add hiding spots so they can retreat when needed.
7Best for Experienced Keepers
This species is generally considered suited to hobbyists with some prior experience, since it benefits from attentive water quality management. Beginners may want to start with a hardier species first.
