Sexing: There are no known external sexual differences. There are however some thoughts and suggestions that there may be some differences in the shape of the bony plates which extend from the head to the edge of the pectoral fins. It has been suggested that the male has a more pointed plate, and the female has a more rounded plate. There is no scientific evidence available to support or refute this though.
Additional Information: Always use a very fine mesh net when transferring this fish. It will get stuck in a regular mesh net making it difficult and time consuming to free. Be careful when handling as its bodily serrations, especially those of larger specimens, can cause injury. Adequate filtration along with frequent water changes are a must for this large specimen.
