Buying Guide: Catfish For The Aquarium
- Tank size and layout: Many Otocinclus and Corydoras prefer planted tanks with soft substrates and hiding spots. Larger species, like certain Plecos, require more space.
- Water parameters: Most listed fish prefer pH roughly 6.5–7.5 and moderate hardness. Maintain stable temperatures to reduce stress.
- Group dynamics: These species are social. Keep them in small to medium groups to minimize stress and encourage natural behaviors.
- Diet and feeding: Most Otocinclus are herbivorous and rely on algae wafers or vegetation. Corydoras are opportunistic bottom feeders that will scavenge leftovers.
- Temperament and compatibility: Peaceful by nature; suitable for community tanks with non-aggressive fish. Avoid housing with large, aggressive species.
- Transportation and shipping: Weather and temperature can affect DOA claims. Ensure acclimation and consider live arrival guarantees when ordering online.
- Maintenance needs: Regular water changes and stable filtration support long-term health, especially for bottom-dwellers.
