Aplocheilus blockii

Aplocheilus: from the Greek απλός (apló) meaning 'simple, plain', and χείλος (cheílos), meaning 'lip'.

blockii:

Native to Sri Lanka and southern India with records in the latter existing from the states of Goa, Kerala, Tamil Nadu, and more recently, Karnataka.

Reports from Pakistan may be erroneous while the species's distribution in certain parts of the Western Ghats mountains in India requires confirmation.

Type locality is given simply as 'Sri Lanka'.

This species is euryhaline and mostly inhabits lowland, often coastal, habitats containing still or slow-moving brackish or freshwater.

It displays a preference for habitats with surface vegetation or overhanging cover and is commonly found in mangrove swamps and rice paddies.

Minimum base dimensions of 45 ∗ 30 cm18 ∗ 12 in or equivalent are recommended.

Aplocheilus 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.

Not 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.
