Conor, as I said a few days ago, breeders all have different
opinions about almost everything. Ask one and he/she will say it is
OK to breed two DTs, and ask another and they'll say "No way
Jose!". But you come knocking to the right door because, just
like you, I also LOVE DTs (and always have). In your endeavor to
produce DTs, here are a few things to know (and to lookout for):
|DT genes improve finnage. A ST
betta carrying DT genes will have a better dorsal and generally
speaking, better finnage. All my lines carry DT (or just about)
for that reason. Also I like to have both a ST and DT version of
each line whenever possible.
|DT bettas have a huge dorsal
and two tail lobes. They also have shorter bodies than their ST siblings.
They can look a bit more stubby, as the body is not only shorter
but also a bit more wide.
|Because they are shorter, DT
have less space for internal organs. Usually does not cause any
problem unless you overfeed. They are twice more prone to
swimbladder problems than ST.
|DT almost never blow their
tails :). ST with large tails (HM) almost invariably do (sooner
or later LOL).
|DT bettas can come out with
bent spine, or pinched peduncles, or crooked bodies. This is
more predominant in recessive strains because they are more
inbred. When breeding to produce DTs, expect to lose a
percentage of the spawn to slight deformities. BTW, ST also can
have similar problems, but it is less prevalent.
|Breeding two DTs together will
cause the bodies to get even shorter. Each time you breed two
DTs you shorter the bodies farther more. Results? Short stubby
bodies, thick, and a lot more chances of deformities (crooked
spines, etc). That is why a smart breeder will avoid this combo
at all cost.
|The best combo is to cross a ST
carrying DT to a DT betta. You will get 50% of DTs and 50% of
nice ST carrying DTs (with nice dorsals and better finnage).
Almost all my lines have such characteristics. Notice that I
never pair a DT female to a DT male, instead I will send a DT
male with a ST sister carrying DT. I was one of the first
breeders out there to sell bettas paired like that. Used to be
that breeders would sell ST pairs or DT pairs, the DT pairs
comprising of two DT bettas :(. So people would have to buy two
pairs (one ST pair and one DT pair) to be able to get that DT to
ST/dt combo. In an effort to save people money, and because I
wanted people to get the best results possible, I started
pairing up bettas the "right way" and selling all my
lots paired that way.
|However, what if you are in a
situation where all you have are two DT bettas? For example, you
get a spawn of blue bettas and in there are only two purple with
green fins bettas (doesn't exist, I am just trying to make a
point here). These two SUPER RARE bettas should be bred together
to increase the chances of getting more like them and so to not
forever lose this chance of having a new color created. You will
breed the two DTs together, and you will be OK, for the most
part most of the fry in the first generation will be OK. But
this is only OK, as a one time deal and in desperation LOL. Then
you would have to cross back to ST blue siblings (hopefully
carrying the same genes that caused the purple/green mutation).
To create new strains, and to
maintain them (as to NOT LOSE THEM) you sometimes have to compromise
and in that respect, breeding two DTS is totally acceptable. Just
understand that you will have to cross back to STs soon if you do
not want your line to produce nothing but deformed fish.
I hope the above has helped all of
you out there who love DTs.
