 The breeding aquarium for the rummy-nose tetra, in addition, needs to be sterilised prior to use, as the fish produces eggs that are notoriously sensitive to bacterial and fungal infection.Use of an antifungal agent is strongly advised once spawning is completed in order to prevent various fungi from attacking the eggs.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.
