Breeding Report: Austrolebias nigripinnis
Water conditions: Moderately soft and acidic, 20-23oC
Spawning Method: Peat (or similar) spawning substrate
Sex ratio: Roughly equal
Breeding difficulty: Easy
Success: Very successful
Other Comments: I first kept nigripinnis 28 years ago in a community tank. Fisrt bred them about 20 years ago. Live foods are essential from hatching for about 3 or 4 weeks, then frozen or meaty foods. I don't use strong lighting as I don't grow plants in spawning tanks. Avoid strong water movement from filters.

Breeder: (1 years experience with this species)

Location code: Carmelo
Water conditions: Moderately hard and alkaline, 20-23oC
Spawning Method: Peat (or similar) spawning substrate
Sex ratio: Somewhat female heavy
Breeding difficulty: Very easy
Success: Fairly successful
Other Comments: Always seem to get some bellysliders - around 20-30%. Incubated for 3 months in moist peat. No canibalism seen, refused to eat anything but live food though. Needs enough peat to completely bury itself - too little and they bang their heads on the bottom of the container and give up. Kept in 2F to 1M trios - more than 1 male leads to violence!

Unsuccessful

Breeding Report: Austrolebias nigripinnis
Water conditions: Moderately soft and acidic, 20-23oC
Spawning Method: Peat (or similar) spawning substrate
Sex ratio: Roughly equal
Breeding difficulty: Easy
Success: Fairly unsuccessful
Other Comments: This is an easy fish too keep as long as you don't pay any attention to the books which say the eggs need a 4 to 5 month incubation period. They need 3 months. Any more and you get belly sliders. The males will fight amongst each other but that is about all the aggression there is. They will eat frozen foods, flake etc... Fry grow rapidly and mature at a small size.
