Dichotomyctere ocellatus commonly known as the "figure 8" puffer or eyespot puffer, is a pufferfish found in freshwater in South-east Asia. It is known from the lower reaches of the Mekong (Cambodia), the Peninsular Malaysia as well as Borneo. They are colourful fish, with greenish yellow patterns on their backs. These patterns vary greatly from fish to fish, but the markings either side of the caudal fin resemble the number eight, or eye-spots. Figure 8 puffers are relatively peaceful among Tetras, and have been kept successfully with other fish such as bumblebee gobies and mollies, but as with all pufferfish there is a risk that tankmates will not be tolerated.
