Habitat
Biome: Fresh water . Benthopelagic.
Ecology: Found in springs
and spring-fed streams
, rarely observed in the open water
of some lagoons
of the lake
(Seegers and Tichy 1999). Inhabits waters rich in sodium and chlorides and temperature
ranges
between 16–40°C (Reite et al. 1974). Omnivorous
. They take algae from stones
as well as live food
. The basic natural diet
is blue-green algae. Sometimes insects are gulped from the water surface. Bacteria are also taken from the water surface (Seegers and Tichy 1999). The juveniles
are carnivores
feeding on invertebrates
, eggs
and larvae. There seems to be no distinct
breeding period, although there may be a breeding maximum in December/January, which coincides with the hottest period of the year. Male builds nests
(pits), which are not aggregated nor grouped in large numbers (Seegers and Tichy 1999). Max
