At this stage, antifungal agents to protect the eggs should be added, and indeed are vital in the case of this difficult, sensitive species. An additional problem is that gender differentiation is difficult by visual inspection alone, making pair selection partly a matter of luck unless an obviously gravid female is available for selection. However, if captive reproduction is to be attempted, the rummy-nose tetra needs soft, acidic water, as Tropical Fish Hobbyist magazine recently reported that research work upon these fishes indicates that high levels of calcium ions in the water induce sterility in these fishes. Can be bred in a similar way to other species in the genus. Namespaces Article Talk. The species is not noted as a particularly egregious egg eater unlike, for example, the lemon tetra —see that article for notes on egg-eating behaviour in characins but it is still advisable to remove the parents once spawning is completed. Seriously Fish. Lifespan for the rummy-nose tetra in the aquarium is usually 5 to 6 years with careful maintenance. Most experts agree that a full revision is required, with the likely outcome that many species will be placed into new or different genera. The fish is interesting in that it can act as a "mine canary" in an aquarium, alerting the aquarist to potential pollution problems in an aquarium.
Even if you've narrowed it down to the tetra family, each member has a unique appearance to tempt you. Rummy nose tetras display a variety. The rummy-nose tetra (Hemigrammus rhodostomus) is a species of tropical freshwater characin fish originating in South America, popular among fishkeepers as.

Distribution. Rio Orinoco and the lower Amazon basin in Venezuela and Brazil.
A small air-powered sponge filter bubbling away very gently is all that is needed in terms of filtration.
In common with numerous other tetras, these fishes are particularly fond of live bloodworms these are the aquatic larvae of a midge belonging to the genus Chironomus and will also devour live Daphnia avidly. Consequently, compatibility of these fishes with cooler water fishes is contra-indicated: for example, panda corydoras would be a bad choice of companion as these fishes prefer lower temperatures, and there is little overlap in the temperature ranges of the two species.
These will hatch in hours, with the fry becoming free swimming a days later. Under these conditions the true beauty of the fish will be revealed.

Like all Hemigrammusthe taxonomic status of this species is currently Incertae Sedismeaning uncertain.
The second thing we can examine is the caudal peduncle of the fish. Condition these with plenty of small live foods and spawning should not present too many problems. The species most often sold as such is, in fact, the firehead tetra, H. When the females are noticeably full of eggs and the males are displaying their best colours, select the fattest female and best-coloured male and transfer them to the spawning tank.
Needless to say, given the above remarks about likely sterility if the fishes are maintained in water whose chemical parameters are incorrect, prospective parents must be maintained in soft, acidic water throughout their lives if they are to remain capable of reproduction.

|The first, is by the extent to which the red colouration on the head of the fish extends into the body.
