General: The Rummynose Tetra (Hemigrammus bleheri) is a small community species with a vibrantly colored forehead. This tetra is extremely peaceful, colorful, and a great addition to any small community planted tank with stable water chemistry. Naturally, this fish resides in the black water streams of the Rio Negro in Brazil. The environment in these areas consists of submerged driftwood, large amounts of vegetative matter, and a dark water stain that is derived from the natural decomposition of organic materials.

Reproduction: The Rummynose Tetra is difficult to breed, in comparison to other small community species. When attempting to breed any fish, it is best to closely mimic that species natural, environmental conditions. A slightly acidic pH of approximately 6.2, soft water hardness of 1-3 dGH, and a water temperature of 84 degrees Fahrenheit should be maintained in order to encourage breeding behaviors. Heavily planted tanks will optimally provide the structural habitat needed for Rummynose Tetra fry to survive.

Preferred Water Chemistry: Acidic (5.8 to 7.2 pH), soft water hardness (1 to 3 dGH)

Aquarium Diet: Brine shrimp, baby brine shrimp, blackworms, general flakes, omnivore pellets, Spirulina

Dimorphism: It is difficult to determine the gender of Rummynose Tetra. Once mature, the female will take on a more gravid appearance.

Compatibility: The Rummynose Tetra is compatible with a large variety of small community species such as other Tetra, Danio, Rasbora, Corydoras, and South American Dwarf Cichlids (Ram, Apistogramma). Regardless of differing water chemistry preferences, it is possible to keep Rummynose Tetra with Livebearers such as Guppy, Swordtail, and Platy.
