Diet
Write a noteEditAplocheilus spp. are surface-dwelling predators preying on both aquatic and terrestrial invertebrates.
In the aquarium they will learn to accept dried foods in most cases but should also be offered regular meals of small live or frozen fare such as Artemia, Daphnia, chironomid larvae (bloodworm), etc.
Reproduction
Write a noteEditNot difficult. This species will deposit eggs in woollen mops, fine-leaved plants or mosses, or filamentous algae depending on what is available.
Incubation is 10-15 days and the fry will initially require infusoria-grade food until large enough to accept Artemia nauplii, microworm, etc.
