<p><span style=\"font-family: \'Times New Roman\',\'serif\'; font-size: 10pt;\" lang=\"EN-US\">The fish species Amphilophus timaculatus (Gunther, 1867) commonly known as Trimac is recognized for beautiful colors with distinct spots in its body. Due to these coloration and relatively easy cross spawning abilities, they are wrongly known to be flowerhorn. As a result, it brings problem about species identification. Hence, the principal objective of this study is to describe the variation in body morphology of the species as well as its sexually dimorphic traits. Using landmark-based geometric morphometrics, a total of 60 (30 males and 30 females) specimens were analyzed. Results showed variations mostly on head region of male (RW1 to RW6) and female (RW1 to RW6) and caudal region of male (RW2, RW3, RW5) and female (RW3, RW4, RW5, RW7). Discriminant function analysis showed significant variation (p&lt;0.05) in body shapes between males from females. Head region variation could resulted from sexual selection, whereas, elongated fins from ecological selection of species.</span></p>
