Delphax Corydoras Fish Guide
Delphax Corydoras, also called False Blochi Catfish, is a small, armored catfish with a soft, pale body and darker markings. It is popular among hobbyists because it is peaceful, curious, and has a cute "bottom-dweller" style of life. It looks unique with its band-like patterns, and it moves around in a group, which makes it fun to watch.
Delphax Corydoras Origin
- It comes from South America, especially from the Inírida River and the upper Orinoco River basin in Colombia.
- The name delphax means “young piglet,” referring to how it forages (sniffs around) in soft sediment for food.
Temperament
- Very peaceful fish; enjoys being with others of its own kind. It’s not aggressive.
- Because it is schooling/shoaling, it feels safer and happier in groups.
Compatibility
- Good tank mates: other peaceful small fish like tetras, rasboras, pencilfish, etc. Also, other bottom dwellers that are non-aggressive.
- Avoid: Large aggressive fish, or fish that pick on barbels or disturb substrate too harshly.
Delphax Corydoras Price Range
- ₹1,500 to ₹3,000 (If imported or rare)
- ₹800 to ₹1,500 (If locally bred)
- Additional costs (shipping, customs, acclimation) can raise the final cost.

Water Temperature

Water Type
Fresh Water
PH Level
6 - 7.5
Delphax Corydoras Tank Type
- Freshwater only. Soft water and gentle currents are preferred.
Aquarium Size
- A group of Delphax Corydoras should have enough space: at least a tank with base dimensions like 90 × 30 cm.
Water Conditions
- Temperature: 21 ‒ 26 °C (≈ 70-79 °F)
- pH level: 6.0 ‒ 7.5 (slightly acidic to neutral)
- Water hardness: Soft to moderate hardness (2 ‒ 12 dGH)
Environment Needs
- Substrate: Soft sand is best for use as a substrate. This keeps their barbels, whisker-like feelers, safe. They can be injured by gravel or sharp edges.
- Decorations: Driftwood, along with rocks, also constitute decorations for shade as well as hiding spots. Natural debris or leaf litter replicates their wild habitat.
- Lighting: Moderate lighting is fine. Bright specific lighting is pointless. Shade helps them feel secure.
- Filtration/water flow: Gentle to moderate. They naturally live in slow-moving waters.
