Occurrences in Sri Lanka are mostly limited to the western coast and pertain to North, North Western, North Central, Western and Southern provinces but there is at least one record from Batticaloa in Eastern province suggesting it might be distributed around much of the island. It also occurs in freshwater habitats, however, including a number of inland lakes in Sri Lanka although it appears to have been introduced intentionally. There exists observational evidence to suggest that it can breathe atmospheric air to an extent, probably an adaptation to conditions of low suatensis oxygen.

suuratensis This species can be maintained in fresh or brackish water so long as acidic conditions are avoided. Observations of wild fish suggest it to be something of a generalist with a tendency to suratenxis aufwuchs and filamentous algae from solid surfaces.
Best avoided are territorial or otherwise aggressive species, including other cichlids unless the aquarium is very large, and those that require soft, acidic water. When maintained in smaller numbers weaker specimens can become the target of suratemsis abuse by dominant individuals or the group may fail to settle and behave nervously. Males tend to be larger than females of equivalent age but sexing of non-nuptial individuals can be tricky.
This species is a biparental substrate spawner which forms temporary pair bonds when reproductively active. Observations of wild fish in Sri Lanka suggest that there are two such periods each year represented by the dry pre-monsoonal December to April and monsoonal June to September; the monsoon season is dry in parts of Sri Lanka seasons when water salinity increases and turbidity decreases, the latter thought to suratenssis the fish via improved visual contact between adults and fry.
Eggs are deposited in typical fashion and attached via short filaments permitting a degree of movement. Both parents participate in guarding the territory and general brood-care such as fanning and mouthing the eggs to keep them sediment-free.
Incubation is approximately hours depending on temperature with the fry swimming freely in a further days. Prior to hatching the adults excavate a number of nursery pits in the substrate surrounding the spawning site and the fry are moved between these until their yolk sacs are absorbed.

This species is not especially popular in the aquarium hobby but is an important food fish across the majority of its range with some populations having crashed since the turn of the 21st century due to over-exploitation.
