Carinotetraodon: Latin, carina = keel shaped, shell + Greek, tetra = four + Greek, odous = teeth
Although quite adaptable Carinotetraodon borneensis prefers soft acidic fresh water which is of high quality. These fish have a low tolerance for nitrogenous waste in their environment. If keeping a group of these fish or if keeping them with other species it is important to provide lots of cover.
Carinotetraodon borneensis are nocturnal, they will be most active at night or just after lights out. They should be fed when there aquarium lights have gone off for the day.
Carinotetraodon borneensis eat small inverts, they will readily accept shellfish of a suitable size, blood worms, brine shrimps, daphnia, snails, small earthworms, terrestrial insects such as small crickets, small meal worms (occasionally). The key to keeping these fish healthy is to offer a varied diet.
Carinotetraodon borneensis seems to be less prone to 'over grown beak' problems than other puffer fish.
Territorial, Carinotetraodon borneensis may be kept in pairs or in small groups provided that each individual has plenty of space and that adequate cover is available. Other species which are fast moving (such as barbs, danios ect can also be included but slow moving long finned fish will be bullied or even killed.
Males are more colourful and they have a black blotch on the base of their dorsal fin.
Unknown, but it is always a concern when a species has such a limited range as Carinotetraodon borneensis.
Rarely seen in the hobby but a lovely looking fish. Very similar to its close relative Carinotetraodon lorteti
