Wow......so fish aren't like cats where if they mate with someone of the same family they could be deformed or handicapped in some way??
That's strange......
.............I wonder why fish are different!??
Good luck breeding your bettas!! They are very colorful and should result in some really pretty babies

for those interested in "betta science" this quote sums it up pretty well -
Inbreeding Vs Linebreeding:
"In order to maintain a particular strain of bettas, there are two commonly employed ways to do so: inbreeding and linebreeding. These two methods of breeding keep the line pure and result in fish that show very selected and specific traits, both good and bad. No out-crossing is required to keep the line viable and fertile for many generations.
Inbreeding is to continuously cross sibling fish from every generation to produce the subsequent generation. For example, starting from the original pair, they produce a batch of about 200 fry (F1). Once mature, a few pairs are selected from the matured fish (F1), and then spawned. Again, from each of the spawns (F2), siblings within the same spawn are used to throw the next generation of fish (F3). Every time a pair is selected, they are chosen primarily for particular traits that are exhibited by that line. This goes on for several generations, with the occasional backcrossing every 5-6 generations. Backcrossing is when a male from one of the spawns with another female from a different spawn are matched together. Note that no new ?genes? are inherited into the line, as the fish all come from the same original pair.
Linebreeding is used to fix a specific trait expressed in a particular fish. This is especially important when it is a new and unique trait. The fish with the new trait(s) is matched with another fish, preferably a sibling or one showing somewhat similar trait(s). Assuming the unique trait(s) lies in a male fish, a female will be chosen (with as much of the wanted trait(s)) from the male?s offspring (1st generation), and crossed back to the male to throw the 2nd generation. From the 2nd generation of fish, another female is selected to cross back with the original male. This goes on for as long as the male is alive. Once the male is no longer available for spawning, a male from the 1st generation batch will be used to match with a female from the youngest generation available. As this carries on, the wanted trait(s) get more and more evident on the entire batch, and eventually come to a point where the spawn throws a certain percentage of fish looking exactly like the male (or at least with the wanted trait(s))
One point to note is that, regardless of whether in- or line-breeding is used, the breeder must be able to select fishes that do not carry to much of an anomaly/bad trait(s), such as crooked spines, fin curling, small sized fish, etc. This is due to the way these breeding methods narrow down the genetic spread and produce fish that are very similar to one another. This will isolate both the good and bad trait(s), so care must be taken to ensure that as little of the ?bad? trait(s) are filtered into the characteristics of the line."

( Crowntail I think ) And My newest Crowntail Male ( RUBY ) Well Im wondering how my babies are going to come out. 
It really is pretty much impossible to know what the offspring of that pair will look like without any genetic background. They probably carry many different genes for red, blue, etc, so their babies will be a mixed bag. That's always the way it is with pet store bettas, their offspring will most likely look nothing like them!
, but I get the overall jist.......I think
