Breeding Report: Austrolebias affinis
Location code: Durazno
Water conditions: Neutral, 20-23oC
Spawning Method: Peat (or similar) spawning substrate
Sex ratio: Somewhat female heavy
Breeding difficulty: Easy
Success: Very successful
Other Comments: Very beautiful fish. One of the smaller Austrolebias. I get about 3 females to every male. Incubation 8 to 10 weeks at room temperature. Will take BBS as a first food.
Breeder: Eric Beyer, Midwest US (2 years experience with this species)
Date this record created: 13th June 2008
Breeding Report: Austrolebias affinis
Water conditions: Moderately soft and acidic, 20-23oC
Spawning Method: Peat (or similar) spawning substrate
Sex ratio: Somewhat male heavy
Breeding difficulty: Easy
Success: Fairly successful
Other Comments: it is wise, to seperate females from males for growing up. They like weekly water-changes (50%) - breeding easily, lots of eggs, incubation-time is about 100 days.

Average success

Breeding Report: Austrolebias affinis
Water conditions: Moderately soft and acidic, 20-23oC
Spawning Method: Peat (or similar) spawning substrate
Breeding problems: Poor fry survival rate
Sex ratio: Roughly equal
Breeding difficulty: Average

Other Comments: Generally non-agressive and breeding well in a group of 6+ fish 50:50.
Breeder: David Baker, Maidenhead, UK (1 years experience with this species)

Unsuccessful

Breeding Report: Austrolebias affinis
Water conditions: Moderately soft and acidic, 20-23oC
Spawning Method: Peat (or similar) spawning substrate
Breeding problems: Poor egg survival
Sex ratio: Roughly equal
Breeding difficulty: Difficult
Success: Fairly unsuccessful
Other Comments: High temperatures, over moist peat during storage, and extended storage times (over 3 months at 23C ) will cause fry deformities. Best results are from 3 months at 21C max. Fry grow rapidly, and are easy to raise, but not many hatch (compared to e.g. nigripinnis.)
