    Scarlet Badis (Dario dario)

    What the Dario dario lacks in stature, he makes up for in personality! Often described as a dwarf cichlid (they're not), this diminutive fish will amuse you with his antics.

As for size--the average male will be about 0.8 inches long and the females are even smaller (0.5 inches). Lifespan for these little guys is between 4 and 6 years.

    Norman's Lampeye Killifish (Poropanchax normani, Aplocheilichthys normani)

    It's weird that you don't see this fish offered for sale far more often since they possess all the traits one looks for in a fish--good looks, robust health and a great personality.

  18. Teaser Paragraph:

    Sparkling Gourami (Trichopsis pumila)

    Simple, yet elegant! No, we're not talking about "the little black dress," but rather the Emperor Black Tetra.

The males eyes are almost an electric blue, while the females, are an equally vibrant shade of green (they practically glow) .

    Twig Catfish (Farlowella)

    Looking like something that just climbed up out of the primordial ooze, the twig catfish's fearsome appearance, belies its gentle nature.

    Pygmy Corycat (Corydoras pygmaeus)

    Cool, is what best describes this cat! Their tiny size and outgoing personality make the pygmy cory, a wonderful addition to any microfish tank.

  24. Teaser Paragraph:

    Threadfin Rainbowfish (Iriatherina werneri)

    There's something very Zen about threadfins; just watching them, makes one feel calmer and more at peace with the world. Maybe their laid back attitude has to do with their native habitat--the slow flowing streams, ditches, billabongs, and lagoons of South Central, New Guinea and the Cape York Peninsula of Australia. If well cared for, they live 3-5 years and grow up to two inches. Mature males and females are quite easy to tell apart--males are more brightly colored and have not only a sail (dorsal fin) they have the fins that look like threads (and where they get their names). Assigning a color to these fish can be difficult as it (color) can vary quite a bit. Health, diet, lighting, where the fish was caught, how they rank in the school, can all influence color. Their basic color is silver/gray. Some will have gold overtones, while others, will not. Their dorsal fins are orange, while the threads are black.

  25. Teaser Paragraph:

    Cherry Barb (Puntius titteya)

    The calm, shallow, waters of Sri Lanka are where you'll find the wild cherry barb. This hardy fish enjoys a lifespan of up to seven years and is a good choice for the beginner. Males are much brighter and redder than the females and will turn an even deeper shade of red, when spawning. Females are lighter in color--sort of a dull orangey/brown with yellowish fins. Their body shapes differ as well, with the male being more slender, and less stocky than the female. Both will grow to around 2 inches.
