Halfmoon (HM) is the term given to bettas that have a perfect semi-circle caudal (i.e. tail)when flaring. Specifically, a halfmoon betta must have a caudal where both ends are exactly 180 degrees apart or more, spreading towards the front. Caudal edges have to be straight or curving outwards, and not bending inwards.

There are a few important things to strive for when breeding for a Halfmoon betta:


1.) Symmetry - the body line that cuts and seperates the caudal into
half.

2.) Balance - the ability to draw an arc that begins from the caudal
and encompasses the dorsal and anal without hitting a snag.

3.) 180 degree caudal with straight and crisp edges.

Few people disagree with the above statements. The only area of
disagreement, or rather a difference in opinion exists in
the 'proportion',i.e. the caudal/body ratio.

When caudal/body is less than 1, you get an 'oval shape'(OS). But
when caudal=body or caudal/body is 1, you have a 'circle'(CS). The OS Halfmoons are good, but the CS Halfmoons are truly exceptional, and an excellent model to aspire to.

What to avoid

Just as there are positive things to look for when choosing or breeding for a Halfmoon, there are things to be avoided. Such as:

1.) Unequal fin rays in the caudal. This detracts from the otherwise 'smooth' arch in the HM form, and tends to look choppy or sloppy.

2.) Non straight caudal fin rays.

3.) Outermost caudal fins rays not at or near edge of caudal.

4.) Fringe (ray extensions) on the fins. Many of these have probably been interbred with the Crowntail form. There is a form called 'Half Sun' which incorporates the 180 degree caudal with the protruding fin rays, and these are very pretty! But not desireable in a Halfmoon.

5.) Dorsal that is thin and 'weak', not in keeping with the huge, sweeping HM form.

6.) all other undesirable traits associated with bettas: Crooked back, disproportionate fins, inactive disposition, poor form, poor color, color 'washes' in a solid color betta.

HEJSAN FROM SWEDEN EVERYONE! Everything in Sweden is going well, although I'm still busy learning the language and coping with a newborn, so it will be a bit before I'm as active as I'd like with the fish. This is a Facebook update! I have created a new BettySplendens Facebook page that will be used exclusively for betta-related networking. On the 16th of August I will be going through and deleting most of the people on my personal Facebook page who are not actual friends or family (many of you have become friends through the course of the hobby, and of course will not be deleted). If for any reason you wish to remain on my personal page, please let me know by emailing bettysplendens@yahoo.com, or FB email. Otherwise, go to the new BettySplendens Facebook page and click the 'like' button for more betta-related news and updates :).

Tack så mycket (that's ''Thank you very much'' in Svenskie-land ;))! ~Victoria~

Slight change of plans! I have decided that, instead of reinventing the wheel, I'm going to create a personal FB page and use the old one purely for betta stuff. So if you're on the original page (now called BettySplendens Bettas), please stay put! :P


For all the betta inquiries:
Just a reminder, I am not selling bettas in the US at the present time. I may begin to supply a few select bettas throughout Europe sometime in late Spring 2011. Cheers!


Spotting the Orange Dalmatian
Ever since it first started being widely seen in pet stores around late 2004, the spotted orange betta has taken the hobby by storm. But what exactly is it?


Finnage Variations
Bettas today come in a wide variety of forms, and new ones are being created all the time. Here are the most popular.


Choosing a Betta
There are basically three ways of purchasing bettas. Buying them from a pet store, buying them from a breeder, or buying them online. I'll run through some important things to consider in each of those options.

Defining a Good Crowntail
For the purpose of showing in the CT class, Crowntails are defined as bettas exhibiting at least 33% reduction in webbing versus ray length in each of the three primary fins (caudal, anal and dorsal). This requirement must be demonstrated in all three primary fins but does not need to be exhibited between all rays to meet the minimum requirement to be classified as a Crowntail betta.
