betta

Rhoad, Kalat, and Lopfer (1975) showed that the agonistic display in Bettas is more vigorous when they are presented with a male of the same species, followed by a mirror image, a moving model, and finally, a stationary model.

Twelve adult Bettas (Aqua Mundi, Bauru/SP) were used for this experiment, experimentally ingenuous, kept isolated in individual tanks (14 x 6 x 11 cm), with controlled lighting (12/12 hrs, cycle beginning at 7:00 a.m.), average Ph level at 8.0 and average temperature of 22[degrees]C.

Male Bettas were obtained from several commercial sources.

ABSTRACT: Oxygen uptake/gram/hour (V[O.sub.2]) was determined for Siamese fighting fish, Betta splendens, denied access to the surface either in mirrored or non-mirrored (control) test vessels.

But recent activist efforts targeting betta fish are aimed at turning the public against retailers and manufacturers, and this could have a significant impact on your business whether or not you sell bettas.

Storefront sidewalk demonstrations protesting the sale of bettas have been organized

<p style="text-align: left;">While we as leaders in the responsible pet trade share the concern for animal welfare expressed in Kristin Hugo's recent piece on betta fish and encourage everyone who owns or cares for animals to consistently monitor their living conditions, we are concerned by the numerous misrepresentations in the piece which paint an inaccurate and misleading picture of the way the responsible pet trade treats bettas.

She states that "They do not naturally live in tiny puddles in the wild, despite rumors" and links to an article that actually says "[s]ince they can live in virtual puddles in their natural habitat, they can survive in small, oxygen-deprived environments." Bettas often live in small streams that will dry up into a series of puddles during the dry season.

If there was a popularity contest for fish, bettas would win, hands down.

"For many busy parents, a fish is the perfect introduction to teaching their young child responsibility and proper pet ownership, and bettas are the perfect fish for novice fish keepers, which is helping drive their popularity," said Marissa Kactioglu, product development manager for Penn-Plax (http://www.penn-plax.com/).
