Introduction

Etroplinae is a subfamily in the cichlid family of fishes.

The subfamily includes two genera:

  • Etroplus : Etroplus are the only cichlids which are native to India and Sri Lanka, Asia .

  • Paretroplus : Cichlids belonging to genus Paretroplus are native to Madagascar, Africa.

A remarkable features of this family, is the development of the front part of the gas bladder and corresponding changes to the posterior of the neurocranium(back part of the skull and houses the brain) to create a direct connection between the gas bladder and inner ear .
This feature is not seen in any other Cichlid families.
This allows fish of this genus to have remarkable hearing power.
