Hmmm... the whole doubletail thing is confusing me, I've heard a lot of things about DT/DT crosses being undesirable because they cause deformities or even homozygous doubletail being fatal... I don't really understand it, can somebody shed some light on it? I've just dug these up on Aquabid and I'm seriously considering shelling out some major moolah for them - as in $65AU each, which is one month's wages plus pocket money, EACH. I think they're worth it, but I would love some opinions.

The doubletail mutation is virtually unknown in Australia, in the year I've been seriously paying attention to bettas, I have seen exactly one doubletail, and TBH I would have thought it was an injury if not for the sticker saying it was a doubletail and tripling the price over the other bettas. The lobes were very uneven and the dorsal fin looked hardly bigger than normal. So if that's worth $30 at a pet store (another fish from the same shipment, the only other doubletail and presumably of similar quality, had sold the day before, which was the day the shipment had arrived, for $30-35) I think I could get at least $20 for some decent quality doubletails if I bred these (and that's no guarantee given the luck I'm having at the moment :shout: ). I mean, the fish I saw for sale was fully grown, crowntail (which is pretty common in Australia), a boring bluey colour with red wash and no information on its history was available. A single tail halfmoon (there is an established breeding circuit of HMs in Australia) will sell for $50-60 at three months from a breeder, and that's not for international standard or anything, that's just for a true 180 with good colouration (solid/single butterfly).

So can somebody tell me a) whether there's any point asking for sibling females or if I should just use an unrelated PK or HM girl with similar colours (they aren't hard to find). And b) whether these are good fish... I mean, I've fallen for them but still.
In order of preference, #1 is the one I will definitely buy if I decide to go for it, and I might chuck in #2. #3 is hot, but I can't afford three.

Obviously, I know nothing about this, but I do recall Modaz or was it Bronzecat? talking about having to outcross on doubletails to avoid nasty deformities.
So, since my posting will bump this up, if you haven't been answered on this elsewhere already, maybe the question will be noted now.
 
Putting together DT x DT does produce more defomities in the fry but using DT with any other single tail Betta can improve on the branching and finnage in the line you are working on.
 
So if I bred DT/HM or DT/PK, would I get enough DT fry out of that cross to be able to work with an actual doubletail line?
 
In your first spawn you probably wouldn't get any, but a high percentage of them would carry the gene. So then you could breed the best siblings from that spawn, that would hopefully give you about 25% DT but it's not guaranteed. Which ever way you do it, it should always be DT x Singletail or Singletail x DT.
 
you could also try asking the breeder of the male you get if they could sel you a single tail female aswell, most would do this!
 
I'm sure they would but it's another $10 or 15 for the fish, plus another $25 import/quarantine - a lot cheaper for me to find a compatible singletail female locally if I should be using a singletail female. I just wanted to know if I should be asking about doubletail sibling females.
 
a single tail locally will need a couple of spawns to get double tails, whereas the single tail i was talking about would be a female with 1 tail from the same spawn, it would carry double tail and therefor you first spawn would have doubletails and singletails

option 1
Dt x St = Dt's and St's

option 2
Dt x any other female = any other tail type carrying Dt
and then either
sibling x
or
Dt(father) x


i think that should help explain it
 
The auction closed with no bids... I've been in contact with the transhippers, both the Australian transhipper (who receives and quarantines the fish) and the Thai transhipper (who sends the fish to her). It would appear that they think the seller is trustworthy, and Preecha says he thinks the fish is still available... I've contacted the seller, so hopefully I may end up with a very very nice DTHMPK.
