Abstract: CICHLID fishes have diversified and innovative characteristics. Identification of chromosomal variation is more upgraded than the identification of morphological character of this fish species. Recognition of special biogeographic patterns is important to understand the genotype of these fishes. This research article will focus on genetic diversity and topologies relationship among the Cichlid fishes. Analysis of different kinds of cichlid variation is essential for enhancement of economic prosperity from the fish cultured ornamental fishes are one of the innovative and wonderful creatures with different characteristics. Demand for ornamental fishes is increasing day by day, though it is providing a huge opportunity for enhancement of economic stability. Nowadays, government agencies have introduced different promotional schemes for boosting entrepreneurship activities. Discussion on ornamental fish, cichlid variety and RAPD will be useful to justify this researched article. The use of RAPD PCR is one of the innovative techniques to determine the subspecies of the selected fish. DNA (RAPD-PCR) is one of the innovative molecular tools to identify the characteristics of genetic diversity. In this case, RAPD fingerprinting is the most effective way to demonstrate the differences of the family, kingdom, species of fish. Genetic variation is enabled to focus on the genetic taxonomic to enhance knowledge on fishes' biodiversity. The proportion of genetic diversity, polymorphic activities helped to acquire knowledge on breeding activities. Genomic DNA of some particular Cichlid Species such as Blue peacock, green jewel has been mentioned in this paper. DNA isolation of the selected fishes has been discussed. DNA fragments of these fishes have been discussed in this project. Recognition of the ecological opportunity helps to increase the adaptability of these fishes. Genetic diversity helps to acquire knowledge on the biodiversity of the fishes. This project will determine the importance of DNA finger printing to enhance knowledge on this topic.
