WHAT TYPES OF BETTAS ARE THERE? The Betta has been bred in many different types, having a variety of different different colours, colour patterns and tail forms. The selective breeding began in S.E. Asia long ago, with breeding of the Plakat Morh, the true Fighting Fish of Thailand , Plakat Khmer, the Cambodian colour form, and the Plakat Cheen, the long-finned, ornamental variety. Modern breeding programmes have greatly extended the range of colours, fin types and patterns so that many combinations exist. exist. These all derive derive from the Plakat Khmer and Plakat Cheen. The main forms and colour types are listed here, with a brief description of their genetics genetics and breeding. At our hatchery, we are developing the Royal Blue/green complex, Crown Tails and the Double-tailed varieties, in an attempt to breed improved Double-tailed Double-tailed Turquoise and and Royal Blue Bettas. Delta Tails and Half Moons Moons will be a future breeding line. We also keep Red, Yellow and Cambodian Bettas. The pictures on this page are not necessarily of my fish but are images gathered from many places places over time. I thank all those Betta growers and photographers whose pictures I have used for their assistance and cooperation.

The Colours in

Betta splendens

dReds

Solid reds are non iridescent colours and must have the colour spread spread evenly over over the body. A clean red red is desirable, without iridescent colours and no fading. Reds range in hue from beautiful, vermillion reds to to deep crimson and red/brown red/brown colours. The quality of the colour varies among strains, with most red Bettas showing some iridescence or other colours to some degree. Any opaque overlay detracts from a good red, giving rise to muted reds and pinks.

A brilliant cherry red is most desired in red Betta splendens without any iridescence or opaque colour to mask the solid red. The Red Loss factor causes Bettas that are red as juveniles to lose that colour as the mature. This factor is present in Cambodians and in yellows and apricot colours.

The ideal colour of a true Black Betta splendens resembles that of the Black Mollie. Black (melano)

Black in Bettas is often a smoky black. Black Lace forms have transparent, smoky fins. Black is one of the most difficult colours to achieve, as the melano gene produces infertile Black females. Several crosses with other colours have tried to alleviate this problem, e.g. Melano x Celophane or yellows.

A smoky Melano with some royal blue

The Melano x Black Lace lines are infertile; Steel Blue females x Melano males and Royal Blue females x Melano males have produced Blacks with considerable iridescence present.

Steel Blue is also sometimes called Metallic Blue.

Steel Blue

This colour has a metallic iridescence when compared to the Royal Blue Betta. Steel Blue results from the allele combination blbl. Steel Blue, Green, Royal Blue, Green and Turquoise Bettas have an interesting genetic inheritance pattern based on the Bl / bl alleles that show incomplete dominance and determine iridescence.



Double Tailed Steel Blues. Notice the additional rays in the dorsal fin of this Double-tailed type-- a characteristic of the dt gene.

Green

Crossings: Steel Blue x Steel Blue gives100% Steel Blue offspring; Green x Green gives100% Green; Green x Steel Blue gives all Royal Blue; Royal Blue x Royal Blue gives 50% Royal, 25% Steel, 25% Green; Green x Royal Blue gives 50% Royal, 50% Green. Steel Blue x Royal Blue gives 50% Royal, 50% Steel Blue Turquoise is a variation of the "green" colouring (BlBl alleles).

Green is the least fixed single colour and varies in shade from fish to fish and line to line. Most Green Betta splendens have a bluish green hue but less so than a Turquoise variant. It is often difficult to distinguish these two hues. Choice greens are dark green. This and the turquoise hues derive from the same alleles (BlBl). The much sought after, dark, forest green is rare.

A green RT female.

Turquoise

A variant of the green, with a distinct blue hue. Consistent colour across the fish is rare. The choice colour contains tones of blue rather than any Green or Yellow shades, to distinguish them from the common green. Fish with colours close to turquoise are often found in Royal Blue and Steel Blue spawns. The ideal is a dark shade of turquoise.



A turquoise HM males

Royal Blue and Corn-flower Blue

The consistent, solid royal blue is the choice form: the genotype Blbl or blBl gives a deep, rich royal blue in the green/steel blue/royal blue complex. The most common form has a dark head and royal blue body and fins. The ideal colour lacks reds and greens. Corn-flower blues are the same genotype as royal blues but with a dark head and corn-flower blue body.

Royal Blue Male Veil Tail

Yellow

Royal blues with red factors may appear violet or purple when young and will lose it if the red-loss factor is present and so produce royal blues. Red loss occurs also occurs in Steel Blue, Turquoise, and Green.

Brilliant lemon yellows or even a butter yellow are the best yellow colours produced so far, although some breeders claim to have produced a golden yellow. Colours that tend to be either a very pale yellow or a yellow-brown tinted are inferior colours. Yellow results from a gene that transforms red so sometimes the presence of red is also visible. Golden yellow Bettas, with golden iridescence, are rare. In my yellow/apricot strain, only the operculum is iridescent gold.

AVT yellow.

A lutino form exists, in which the eyes are yellow, too.



These are yellow pastels of varying intensities. Apricot and Peach

Apricot yellows have a distinct pale orange tint to the yellow. Some yellow Bettas show a faint orange tint to the fins and are called Apricot. To continue the fruity colours, "Pineapple" Bettas are yellows with a distinct black outline to the scales, giving a net-like or pineapple appearance. Pineapple Bettas are pattern form, not a colour type.

A Peach Male Betta.

Clear or Cellophane

Albino

White (Not albino)

Has completely transparent fins, with body fleshcoloured; colour from the body organs can cause the fish to look pink. Eyes are pigmented (not albino).

Rare. A characteristic of any true Albino fish is that the body lacks all pigmentation, including the eyes which appear red. Like Cellophane, these are completely colourless fish and may appear pinkish white or solid white if the opaque factor is present. True albino Bettas have red eyes, with no pigmentation.

Some solid, white Bettas are a truly beautiful dense white due to the Opaque factor. Whites may have black eyes if they are not albino. The image, left, shows blue due to the colour rendering. The fish is white.

Whites of this type have black eyes.



Opaques (Pastels)

The Opaque allele gives the fish a milky white overlay that dilutes the underlaying colours to pastel shades, including the eye colour in most cases. There is an opaque form of each of the main colour types if the Op allele is present. White Opaques appear dense white to opaque steel blue. Pastels can be almost any pastel colour.

Chocolate

Chocolate Betta splendens look brown to the eye, but are actually a black and yellow mix.

Chocolate variants can be bred to yellow to improve colour of both the yellow and the chocolate fry.

Orange

Orange Bettas are a new strain of Betta splendens, and concepts of "orange" varies with individual breeders. I have not seen any true orange Bettas in Australia, except for light reds that look more vermillion/orange than true orange and yellows that have a slight wash of orange/red. How "orange" is orange?

Orange Betta


Perhaps an agreed colour chart would help distinguish true colour classification.


Lavender, Purple and Violet

A lavender Betta is genetically a Cambodian Betta splendens with extended Red and a layer of light iridescent blue-green. Truly Purple Betta splendens are also very new and rare and it appears that the colour results from blending red and blue. My Royal Blue strain throws purple or violet fry that appear violet at their first show of colour and darken to royal blues within a few months, as the red fades (due to the red-loss factor, L) as the fish mature . Truly violet coloured Bettas are rare.

The many colours of aquarium-raised strains of Betta splendens can be grouped into several colour patterns:

"wild type"

Betta splendens or Betta imbellis?


The typical red/brown Betta splendens is a dull red, with some blue/green iridescence. Pictured is a specimen sold to me as a wild type Betta splendens but it looks very much like B. imbellis. The two species are closely related and the modern varieties of Betta splendens may descend from a hybrid of B. imbellis.


solid colours

Any continuous, solid colour covering the entire body as well as the fins gives a fish of one colour. Includes both iridescent and non-iridescent colours, the main colours being red, steel blue, royal blue, yellow, steel blue, green, turquoise, purple, lavender, chocolate brown, black and white. Solid colour forms should have no colour breaks or show any iridescence.

bi-coloured

Essentially, the body is one colour and the fins and tail are another colour. The body and fins can be any combination of the recognised solid colours . There are two types of Bi-coloured Betta: a) dark body types, with light fins, and ... b) light body types, with dark fins (including the cambodian trait). In each case, only two colours should appear on the fish. These colours should be well defined and high in contrast

Butterfly Betta.

new variegated types

A bi-coloured form in which the colour pattern of the body (which may be of any colour) partially blends into the transparent or white fins and tail (body / blend / fin edges). The effect is to create an oval band around the fish, which ideally is separated from the body by a narrow, white or transparent zone. Choice Butterfies have a coloured body with a white blend into the fins and then a final blend back to the body colour towards the edge of the fins. Fins should display a distinct banded pattern, with strong contrast and well defined edges. The bands should also encircle the body of the fish with a well defined oval shape.

<< Pictured is a beautiful fish, displayed on the California Betta Society web page. It shows the trend in modern breeding lines for colour and pattern development. BettaBiz displays some choice new varieties. Variegated types show beautiful patterning that may or may not match the "butterfly" look.

Butterfly: a variegated butterfly type in which the band near the body is particularly wide.



tri-coloured Butterflies (incl. the "Tutweiler" BF)

<< Beautiful tri-coloured "Butterfly" types: while not a true BF in the strict sense, this pattening is more frequently encountered. Some butterfly trains are tri-coloured. Both light bodied and dark bodied forms exist.

"Tutweiler" BF Crown Tail

A notable early expression of this pattern was in Tutweiler"s BF, in which the body is paler than the band closest to the body. However, that pattern was not a fixed strain.

Claire McHendrie's tri-coloured Butterfly: note the enhanced dorsal fin and the lack of ventral fins in this fish.


Above, is Diwa's "Tutweiler", a modern attempt at reproducing the Tutweiler BF in Crown tails bred in Indonesia. The strain is Cambodian based and not yet stable.


White or salmon pink faced Bettas in which the colours are splashed or blotched with no defined borders between the body and the fins or tail. marbled Two types of Marble Betta exist: a) the traditional Marble or Piebald, which is a dark bodied fish with a white head or face and lacking in the colours red, green, blue and steel blue; and b) the Coloured Marble. The fins of the choice Coloured Marble show a sharpedged mix of light and dark colours (red, green, blue, and steel blue) and the face and chin are white or pink / salmon coloured. A Coloured Marble

multicoloured

"Multicoloured" includes those fish that do not fit into any of the above mentioned pattern categories and have two or more contrasting colours. Tri-colours fit in this category. << Pictured left: a tricolour with Cambodian, opaque and variegated alleles. A true butterfly would have a well defined colour break where the fins are blue in this specimen. Many modern Bettas fit this category.

speckled

COLOUR INHERITANCE IN BETTAS


In this colour pattern, the body and fins are speckled with irrigular, dark spots like freckles.


There are four layers of color--the yellow is the bottom most, then black, red, and the iridescent layer is upper most.

*N.B. the Bl & bl alleles determines steel blue, blue-green, turquoise, corn-flower and royal blue colours. Blbl or blBl gives royal blue, BlBl gives green and blbl gives steel-blue. How would you describe this fish? A dark bodied bicolour or cellophane? This is a fish showing the red-loss factor, L. It also has the recessive white eye and double-tail factors, ww & dtdt. It was bred from a Red strain.

"Quasimoto"

Notice how the dorsal fin (upper most fin) almost matches the lower most, anal fin for size- an effect of the dt allele that imparts additional rays to the dorsal fin. Breeding from this fish may improve colour depth in yellows and, of course, throw nice trailing DTs if the female carries that allele, too. Even dt-splits from this line will show improved dorsal fins.

Heart Tails, Fuse Tails and Triple Tails are all due to the dt allele.

Multi-DTs. This fish almost has perfect, evenly sized caudal fins, which is hard to achieve in DTs.


Heart Tails have a partially fused twin caudal fin that gives them their characteristic shape. Fuse Tails have caudal, dorsal and anal fins fused as one entire fin (rare). Triple Tails are very rare.

I have bred from a fish very similar to the above specimen, except that the fins were outlined in royal blue. His body was also pineapple patterned- each scale was outlined in black against a pale body. The dt allele in a single dose is used in breeding to give improved tails and dorsal fin count (bred from one parent only and therefore not expressed as the recessive characteristic).

"clown tails"

Crown tails are also crossed with other tail forms such as short, long, double and delta-tailed forms to give considerable variation.

One of Indra's Java Crown Tails flaring. Note the long, extended, double rays.

The name "clown tails" is a corruption or 'crown' tails, reflecting the attitudes and experience of some growers who have experienced variable (and perhaps disappointing) results in the breeding of this trait.

Other tails types include spade tails, fuse tails, heart tails, triple tails, and pla kat tail forms. I have no information regarding the allele for these traits.
