Bond's Corydoras Care Guide
Corydoras bondi is a schooling cory with a dark midlateral stripe, native to the Orinoco region of Venezuela, Guyana and Suriname.
Compiled by Aquairi from published sources · Published · Updated
Overview
Corydoras bondi, the blackstripe corydoras, is an armoured catfish of the family Callichthyidae described by Gosline in 1940. It is a schooling species carrying a dark midlateral stripe and was previously known in the hobby as C31 before formal identification.
Taxonomy
- Family: Callichthyidae
- Genus: Corydoras
- Scientific name: Corydoras bondi
Habitat
The species is recorded from the Yuruarí River in Venezuela, the Corantijn and Rupununi River basins in Guyana, and Suriname. It is a tropical freshwater fish living near the bottom.
Tank requirements
- Minimum tank volume: 80 L
- Temperature: 22-26 °C (72-79 °F)
- pH: 6.0-7.5
- GH: 2-12 °dGH
- School size: 6 or more individuals
- Lifespan: 5-10 years
- Substrate: soft sand
Diet
Corydoras bondi is an omnivore that consumes worms, benthic crustaceans, insects and plant matter in the wild. In aquaria it accepts sinking dried foods supplemented with small live and frozen items.
Compatibility
A peaceful bottom-dwelling species best kept in groups of six or more. It suits community aquaria with tetras, rasboras and otocinclus and should not be combined with aggressive cichlids.
Breeding
Spawning follows the typical corydoras pattern: the female holds 2-4 eggs between her pelvic fins for fertilisation, then deposits the adhesive eggs in dense vegetation. The process repeats until about 100 eggs are attached and the adults do not guard them.
Breeding Corydoras bondi (Bond's Cory)
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.
