Language English The rednosed tetra (Hemigrammus rhodostomus) lives in schools in shallow waters. OngletsDescriptionDistinguishing featuresThe rummy-nose tetra is easily identifiable thanks to the bright red mark that extends from the tip of the “nose” and the front of the gill covers. Some black and white horizontal stripes form a checkered pattern on the little fish’s tail. The black central line on the tail extends as far as mid-body. That characteristic makes it possible to distinguish the rummy-nose tetra (Hemmigramus rhodostomus) from its cousin the firehead tetra (H. bleheri), which has no black line along the its body. ReproductionThe rummy-nose tetra lays its eggs in open water. These will attach themselves to small roots of floating plants. DietThis is an omnivorous fish that will eat a little of everything. Given the smallness of its mouth, the prey itself can only be small as well. PredatorsIn light of its small size, one would presume that the rummy-nose tetra is prey for many larger species, including fish and insects. HabitatThe rummy-nose tetra lives where there’s a lot of plant life, branches and decomposing matter, in shallow water. Thus it avoids predators. Ecology, behaviourThe rummy-nose tetra is a lively and highly active little fish. In the open water it generally moves in schools. It lives in the company of other small fish like pencilfish, neon tetras and dwarf cichlids. Of a highly independent nature, the rummy-nose tetra doesn’t really interact with other fish in an aquarium setting.
