Doubletails

Sherolyn-Basement Bettas When it comes to pure finnage, the Doubletail has it all. Not only is the caudal double with two tails, but the dorsal fin is also sports a double ray count. For meeting the IBC standard the tail split should be centered and the split should reach all the way to the tail …

Naming the new metallic gene

Sherolyn-Basement Bettas Excepting an interlude for the annual science fair column I have devoted the last several columns to Betta pigmentation. First, we explored the fact that some colors are caused not by pigments but by the manner in which light reflecting from the top and the bottom of a thin crystal (or film) interact …

Copper Gold

Sherolyn-Basement Bettas In 2003 a pair of Gold Bettas commanded the record high bid for bettas on Aquabid.com — $1,000.00! The new color strain took the betta world by storm. Not only was the color completely unique and beautiful — a shiny, pure metallic gold — but it also seemed to breed true: Spawning two …

Metallics and Masks

Victoria Parnell This month I’d like to address two of the recent color types that generate the most questions via email from this website: the metallic and the masked betta. I would like to say by way of disclaimer that, as of this writing, nobody really can claim to have solved all of the mysteries …

Inheritance of Metallic Trait

Sherolyn-Basement Bettas Betta enthusiasts have the deserved conceit of being unusually well informed as the genetics of their fish. That they can do so is grounded in large measure by the relatively large number of single gene effects on form and pigmentation the inheritance of which has been rigorously established. The existence of such information …

Sherolyn-Basement Bettas No other color seems to excite both new and old breeders as much as the metallics and Dragons.

Chocolate Bettas

Sherolyn-Basement Bettas There seems to be a lot of confusion surrounding the so-called ‘chocolate’ betta popular among hobbyists today. What exactly is it? How is it made up genetically? What is the difference between the chocolate betta and the ‘MG’ or ‘pineapple’ betta? What you must first recognize is that the IBC does not officially …

Cambodian-Black and Early Gold

Sherolyn-Basement Bettas Several years ago, I attempted to combine the cambodian body coloring with black finnage. As interesting as it was, it became one of the most frustrating crosses I ever tried. A cambodian female was mated to a black male. The result was a batch of fry exhibiting all of the usual colors, but …

Cambodian Genetics

Sherolyn-Basement Bettas The best example of a cambodian is the traditional or red cambodian which has red colored fins and a flesh colored body (but there are also blue cambodians). The cambodian gene causes a fish to have colored fins and colorless or greatly reduced color on the body. The cambodian trait is a recessive …

Cambodians

Sherolyn-Basement Bettas The light bodied phenotype or group of phenotypes known as Cambodian hasbeen traced to a single recessive gene. It is important to clarify the nature of the action of this gene since older papers I’ve found state that it produces an “unvollstaendige Albino” or a “light pink bodied fish.” A good Cambodian betta has a …
