Corydoras vs otocinclus: roles, difficulty, and compatibility as tank cleaners.
Two popular tank cleanup crew species — each with different specialties.
Corydoras: The "bottom cleaner" that eats leftover food from the substrate. Their adorable sifting behavior makes them popular as ornamental fish too. Otocinclus: The "algae cleaner" that eats algae from glass and leaves. Particularly effective at removing brown algae (diatoms).
| Item | Corydoras | Otocinclus | |------|-----------|------------| | Body Length | 3-7cm | 3-5cm | | Lifespan | 5-10 years | 3-5 years | | Difficulty | ★★☆☆☆ | ★★★☆☆ | | Price | 300-5,000 yen | 300-800 yen | | Cleaning Specialty | Leftover food | Algae |
Corydoras: Those who enjoy the cuteness of bottom-dwellers, those who want to collect species. With over 200 species, the hobby runs deep. Otocinclus: Those struggling with algae. However, feeding can be difficult and they may lose weight once algae is depleted.
