Betta coccina, Vierke
1979
By Stefan vd Voort
Betta coccina
is a small red betta found in Jambi (Sumatra), Johor and Malakka -
in Malakka the species is now extinct - (Malaysia) and was first
described by Jörg Vierke in 1979. The name Vierke gave the small
betta, coccina, means wine-red or claret, a description that
perfectly suits the fish if you look at its color. The only
difference between the species from Malaysia and B. coccina
from Sumatra are little color differences which are common for most
type localities.
Betta coccina
was the first fish of the B. coccina group to be discovered and
a true revolution since we only knew B. splendens varieties
with such a beautiful red color. Plus this species had another
unique mark which will be described later.
This species habitats peat swamps that lie deep in the forests. These
swamps have extreme water conditions, fish have been found in water
with a pH between 4.0 – 6.0, a dH between 0.0 – 4.0 and a kH of 0.0
with the water temperature being around 24° to 27°C. The reason why
the temperatures are that low compared to the savannah habitats of
B. smaragdina and B. splendens is because the puddles, in
which Betta coccina lives are surrounded by trees that stop
almost any direct sunlight resulting in shaded, cool water. The
water is tea-colored as a result of leaf litter that falls in the
water providing the water conditions described above. In water this
soft and acidic there’s not much chance for plants to survive with
the exception of the few Cryptocoryne species.
These habitats are known for drying up during the dry season when
there is no rain. All that’s left are small puddles and wet layers
of leafs both in which this species manages to survive until the
next rainfall. This is characteristic for the B. coccina
group.
Description
B.
coccina
reaches a total length of 5,6 cm, both sexes share that length
although females can be a little smaller than males. The first
description refers to the male. The body is sometimes slender and
sometimes more B. smaragdina shaped, it depends on the
individual fish. The color of the body can differ from light to dark
brown but also from bright to wine-red. It’s common that male shows
a dark brown body with two horizontal lighter brown bars running
from the eye to the start of the caudal fin. Their eyes are bright
blue. The dorsal, anal, caudal and pelvic fins are bright to
wine-red and in adults the dorsal and caudal fins have a white edge
which is black in the anal and pelvic fins. The quills are gold to
red. Both sexes possess wine-red, blackish spots in the dorsal and
caudal fin that sometimes also has white spots in male specimens.
The pectoral fins are transparent. The unique mark that this species
and a lot of other species of the B. coccina group have is a
bright blue blotch on their sides! Only young males possess such a
spot and as the male grows older the blotch slowly disappears. Now
and then the blotch may also chance in a blue, bar like figure.
However the spot is not a rule for Betta coccina, there are a
lot of recordings where the males did not have the spot and it’s
even been described some males have the spot on one side of their
body but not on the other!
Conspicuous is the fact that the lateral blotch is a spot where other
B. coccina target their attack on, mostly just gentle pushes
with the mouth.

Females are duller versions of the males, shorter fins and less
colorful but by all means not less beautiful when ready to spawn.
Their horizontal stripe pattern, a female her most common pattern,
runs from the beginning of the caudal fin over the whole body and
through the eye and on the lips, creating a beautiful mask like
image. Males also show this mask like image though rarely. I don’t
think it’s necessary to go in deeper on the species their
appearance, the pictures speak for themselves.
This species is not a very peaceful one but several males can be kept
together. They do tend to be even more aggressive when the male is
constructing a nest or when they are spawning and of course after.
In the two latter the female becomes more aggressive also, sometimes
even more than the male which is kind of uncommon since it’s in the
male’s character of most betta species.
This species can be very shy and if so tends to hide all the time and
rarely come out but there are a few tricks to reverse that which
will be discussed later on.
Differentiation from Betta livida.
B.
coccina
looks a lot like B. livida which is from Selangor and the
latter has often been mistaken for Betta coccina. The reason
why can be noted from the pictures of both species. However there
are small differences between the two species, mainly coloration
differences. In B. livida both sexes possess the lateral blue
blotch and in B. coccina only the male has such a blotch plus
in the latter named species it’s easy to tell whether it’s a male or
a female while in the first named species both sexes look so alike
it’s close to impossible to determine the sex based on coloration
and fin length. Another, however minor, difference is that B.
coccina
has black tipped pelvic fins where B. livida has greenish,
white tipped pelvic fins and the species grows somewhat smaller, 5
cm, than B. coccina. What also helps to differentiate
Betta livida from B. coccina and other species is that
B. livida has two vertical gold bars on the operculum. Both
species seem also to be different in their breeding behavior. B.
livida
is easier to spawn and cannibalism has not been witnessed in B.
livida. Another conspicuous difference is that both parents tend
to the fry for the first few days.
The B. coccina tank
Betta coccina
requires more attention than B. splendens. I’m aiming towards
the water conditions that must be maintained and monitored at least
twice a week to make sure the water has the right pH, dH and kH
values, and if the water is not polluted what can result in death on
longer terms and disease in shorter terms.
Water changes with prepared water, meaning that the same conditions
are gained as the water in the tank, should be carried out at most
once a week or at least once in two weeks with caution. The amount
of water to be changed should be around 20% to 30%. All the values
mentioned earlier will do. B. coccina are not very active
fish so a small sized tank will do fine. Personally I use 60 x 30 x
30 cm tanks for all my betta species. Height of the tank is very
important because this small red betta needs to come to the surface
for air and it’s best to make his swim as short as possible.
Remember that Betta coccina lives in shallow puddles
sometimes less than 20 cm deep! A tank with 30 cm in height is the
maximum for me. Also make sure the tank is covered because they are
great jumpers! The tank can do without a filter when you do regular
water changes but even if you do I still recommend using a small,
slow running filter. All that there needs to be in the filter is
highly active peat granulate and a layer of filter wool to catch the
dirt.
The tank itself must resemble their natural habitat, meaning to
heavily plant it and dim the light as much as possible. Instead of
heavily planting the tank but filling it with leaf litter would be
more natural but I’m not too fond of that because the leafs will
start to decompose within a week or two. That means the leaf litter
constantly has to be replaced by new litter what will disturb the
fish. Instead, a heavily planted tank will do great as a substitute
with maybe a few oak leafs where one likes it.
Betta coccina
likes to stay near plant cover and will try to avoid the open water
as much as possible. To create as much darkness as possible the best
thing to use at the bottom of the tank is black gravel and make sure
the back of the tank also has a black background, all this will make
B. coccina feel good and a little less shy. The plants that
can be used form only a small list; Cryptocoryne species,
Microsorium pteropus, Anubias species, Ceratopteris
pteridiodes, Ceratopteris thalictroides, Vesicularia dubyana and
on the surface Salvinia natas, Salvinia auriculata and
Riccia fluitans will do great. Bog- and driftwood can also be
used and gives a very natural effect if placed effective.

If
such an environment is created the species will show their most
beautiful colors and their most interesting behavior. In hardly
decorated tanks they will appear with diminished colors and only
their fins will be colored red with the lateral blotch hardly being
perceptible. They will often remain in corners or near the closest
thing to cover. The tank will hardly be an encouragement to spawn.
But kept under the right circumstances it is one of the most
interesting species known and if all goes well, as described in the
breeding chapter, they will spawn.
Betta coccina
likes to lean on plant leafs, a piece of wood or sometimes just
holding still in open water without moving a fin in any of the
mentioned situations. They hold so absolutely still they can appear
to have died unless a closer look will be taken. You can find B.
coccina throughout the entire tank. Near the bottom, where they
like to lean on the gravel like they do on plant leafs, but also in
between floating plants near the surface. This species, as all other
betta species, form territories after a few days. That is, the males
form territories. Until that time B. coccina could be hardly
described as aggressive, they chase each other now and then but it
won’t come to real damages to the scales and fins. Only pushing each
other with the mouth and occasionally displaying can be observed.
That changes as soon as the males have formed their territories,
more serious chases take place and the occasional bites, yet nothing
that will result in severe damages or worse. A simple flare or look
in the other’s direction is usually enough to scare the other away.
These red bettas eat black and white mosquito larvae, Artemia and
Tubifex. Preferably live foods but frozen will also be taken without
any problems. Tubifex is a food you should be careful with to
prevent the fish from choking and make them fat, even though it’s
their main menu in their natural habitat. I advice to feed them
carefully in small amounts per fish and monitor them instead of
stuffing each fish full of food. That way you; a) prevent leftovers
from rotting in the tank and b) each fish will get enough food
individually. Also maintain a scheduled day when the fish are not
fed, it’s good for their health and their system. They approach
their food very slow to suddenly take a dive at it. Immediately
after they captured the food they dive back into the plant cover
waiting for more.
Breeding Betta coccina
B.
coccina
is a very difficult species to breed. The problem lies in the fact
that the pairs select themselves, and if they don’t like any of the
other fish nothing will happen. Because of this it’s recommended to
keep a few fish together until they form pairs and then they can be
separated from the others and put in a breeding tank. But even when
good pairs eventually form the whole process may take several
months!

To bring Betta coccina in spawning condition they must be fed
well with foods described above and here also, pay close attention
to the water its condition and values.
If
all is going well the pair can be placed in a breeding tank that is
at least 40 x 15 x 15 cm but larger is of course no problem. The
breeding tank doesn’t need as much decoration as their normal tanks,
a few plants and some floating will do just fine. It is advised to
create some hiding places so they can hide from one another. B.
coccina
is a bubblenester and the male builds his nest under floating leafs,
floating plants or in the tank placed tubes. The little trick that
was mentioned earlier is to place one or more of these items in the
front of the tank, that way the fish will show themselves instead of
hiding most of the time if you have shy specimens.
If
the fish are in spawning condition the female will show her
brightest colors and won’t differ much from the male, that is, with
some specimens. Her now red body will show four to five dark
vertical bars and a lighter horizontal bar that runs from the
beginning of the head all the way to the beginning of the caudal
fin. A small white genital papilla will also be present. This
coloration can be seen before the actual spawning. During spawning
the female’s color is more red brownish without any bars on the
flank but with bright greenish scales here and there. From the top
of the head to the dorsal fin and from there to the caudal fin runs
a white bar as if there are no scales, chased B. coccina
display the same bar. The male keeps the same color whether he is
constructing the nest or to the point of actual spawning. The only
difference between spawning colors and normal colors are the bright
green bluish scales of the male, with the blue spot, if he possesses
one, being brighter than normal and than the scales at this moment.
It may also occur that the fins have a brighter red color than
usual.

Ready to spawn females can be become aggressive towards a male that
is not ready even though they form a good pair. In an article by
Jörg Vierke it is explained that such a female could even attack or
kill the male. Before and during spawning males are very aggressive
towards the female what results in damage to the female’s scales and
fins. Yet the female does not seem to mind and doesn’t leave the
nest. This aggressive behavior by the male occurs after numerous
pushes on the side of female B. coccina with the mouth to
induce spawning. This particular behavior occurs in both sexes while
spawning, the female will gently push the male’s blotch with the
mouth to induce spawning. If all goes well the male will be at his
nest as the female approaches him, or if not, she lures him over to
the nest. The two fish may swim around each other for a while of
spread their fins and send waves to one another as a sign they are
ready. The male embraces the female on the traditional betta way.
This only lasts a few seconds and the male ends the embrace while
the female stays in the rigid mating stance for a few more seconds.
Meanwhile the male looks for eggs which he will bring to the nest.
The bubblenest of B. coccina isn’t very large what can be
seen on the picture beneath. This species is not very prolific and
the number of eggs in total is small, 20 to 50 eggs, as is the
number that a female releases at one time. The latter differs from
one to three eggs. The eggs themselves are white and rather large
like eggs of B. bellica, B. simorum and mouthbrooders. This
is the case in more species of the B. coccina group. After
spawning the female gets chased away by the male who will take care
of the eggs and it’s wise to remove the female at this stage. After
36 hours the eggs start to hatch. If the nest is built on the
underside of a floating leaf or underneath floating plants it might
happen the eggs won’t hatch. Then it’s advised to darken the area
above the nest to make them hatch the next time. Now most species
from the B. coccina group are known for leaving the fry alone
and for good parental care for their fry in the free swimming stage.
B. coccina does usually not live up to that expectation so
it’s best to either remove male also or relocate the fry to a small
tank when they reach the free swimming stage, which is reached in
two to three days.

Raising the fry
After taking the fry to a small tank with some floating plants and
Vesicularia dubyana they’ll go in search of food. The first three
days they will find enough themselves and on the fourth day freshly
hatched Artemia salina can be offered to the fry. The young
don’t grow very fast and reach a length of 2,5 cm in 140 days.
Water changes in the fry tank must be carried out very careful
otherwise this could lead to significant losses. If there are
different batches of fry of different ages in the same tank the
older fry must be separated from the younger fry when the older fry
reaches a length around 3,8 cm, because unlike others from the group
this species their fry do eat their younger brothers and sisters.
