2C, and albino phenotype fig. 2D, and two fin morphology traits i. e. , elephant ear and double tail, figs. 3Aand 4A were studied. Before establishing mapping households by crossing folks with alternative phenotypes, test crosses were generated to observe phenotypic segregation of double tail, albino, and dorsal fin recognizing. In distinction, the female fish who were kept isolated did not continue to display the male common behaviours after testosterone was discontinued. A psychology study used male Siamese combating fish to assess the results of fluoxetine, an SSRI used primarily as an antidepressant in humans. Siamese fighting fish were particular as prime models due to having comparable serotonin transporter pathways, which accounts for their aggression. It was found that once uncovered to fluoxetine, male Siamese fighting fish exhibited less aggressive behaviour than is attribute of their species. Similarly, analysis has found that bettas are conscious of serotonin, dopamine, and GABA. There are many species in the genus Betta, the general public of which are very morphologically identical.
