Ansorge's neolebias can look drab and washed out in a dealer's tank. Once it settles into soft, well planted, tannin stained water, it can turn into a glowing red jewel.
Caring for the Ansorge's neolebias
Give Ansorge's neolebias a small, densely planted tank of at least 11 gal (40 L), with gentle lighting. Keep the water soft and acidic, at 75 to 82°F (24 to 28°C) and a pH of 5.0 to 6.5.
It is peaceful and fine alone or in a group, and a group should number at least six. House it only with very small, calm tank mates.
Males in breeding condition flush deep red across the lower body and fins. It is hard to breed.
