The Skunk Corydoras (Corydoras arcuatus) is a mid-sized catfish named for the single black stripe that arcs from its snout across its back to the base of its tail — the source of both its Japanese and English names. Hardy and easygoing, it makes a great choice for beginners. Kept in a group, these corydoras forage together along the substrate, using their sensitive barbels to sift for food — a natural, engaging behavior to watch. A fine, soft sand substrate helps protect those barbels from wear.

关于弓背鼠鱼
Skunk Corydoras (Corydoras arcuatus) is a hardy, easygoing mid-sized catfish marked by a bold black stripe. Beginner-friendly and best kept in groups on fine sand to protect its sensitive barbels.
迎接弓背鼠鱼前需要了解的7件事
1Use Fine, Soft Sand
Corydoras sift the substrate with their barbels to find food, so coarse gravel can wear them down. A bed of fine, rounded sand lets them forage comfortably and safely.
2Keep Them in Groups
Skunk Corydoras are naturally social and do best in groups rather than alone. Group settings encourage their natural foraging behavior and reduce shy, hiding tendencies.
3Peaceful, Community-Friendly
This species is calm and rarely aggressive toward tankmates. It pairs well with other peaceful mid-water fish, rounding out the bottom layer of a community tank.
4Feed Sinking Foods
Their downward-facing mouth isn't suited to catching food at the surface. Offer sinking tablets or pellets, and make sure enough reaches the bottom before other fish eat it all.
5Avoid Sudden Water Changes
Though hardy, this species can be sensitive to sudden shifts in temperature or water chemistry during water changes. Adding new water gradually and matching temperature closely helps keep them stable.
6Watch the Barbels for Health Cues
Shortened or discolored barbels can signal issues with substrate quality or water conditions. Checking barbel condition alongside the substrate is a good habit for spotting problems early.
7Acclimate Slowly at Arrival
New arrivals are more sensitive to environmental change, so take time to match bag temperature first, then gradually mix in tank water before release. Providing hiding spots also helps them settle into their new home.
