Breeding Corydoras bondi (Bond's Cory)
Breeding guidance for Corydoras bondi: sexing and the documented Corydoras genus spawning pattern, with an explicit note that species-specific data is limited.
Overview
Corydoras bondi is an armoured catfish (family Callichthyidae) reaching about 45–50 mm. Its type locality is the Río Yuruari in Venezuela, and it also occurs in the Rupununi drainage in Guyana and the Courantyne/Corantijn system in Suriname. Note: detailed species-specific spawning reports for C. bondi are limited, so this guide anchors on the well-documented Corydoras genus breeding pattern, flagged explicitly below.
Sexing
Females tend to grow larger, and sexually mature individuals are noticeably rounder and higher-bodied than males, most obvious from above when females are gravid.
Conditioning
Condition the group on a varied diet of sinking dried foods, bloodworm and Tubifex until females are full of eggs; the species is a foraging omnivore and should not be left to rely on leftovers. A surplus of males per female aids fertilisation.
Breeding Setup
- Temperature: 20–26 °C
- pH: 6.0–7.5
- Hardness: 36–215 ppm
- Provide glass, fine-leaved plants and/or spawning mops as egg sites (general Corydoras practice)
Spawning Behavior & Trigger
Following the general Corydoras pattern (flagged: not species-specific for C. bondi), a large cool soft-water change with increased oxygenation and flow is used to trigger spawning. The female cups a few sticky eggs between her pelvic fins, they are fertilised in the T-position, and she deposits them on glass or vegetation, repeating until the clutch is complete.
Egg & Fry Care
By the genus pattern, eggs hatch in a few days and fry take small live foods such as microworm and Artemia nauplii once free-swimming. Rear them over a thin layer of sand with excellent water quality.
