can two diffrent types of bettas breed?

yes, bettatalk.com is a very good site, but as serissime said, betta breeding is difficult! i tried a few times and it never worked and i had three males and three females to work with. you truly need to be devoted to your fish and ready for a lot of hard work and potentially some losses if you decide to try and breed your bettas.
 
to go a lil further into breeding and the crossing of different betta splendens. if you have a blue or red male veiltail and any colour and tail type female, the fry will have a large chance of being mostly blue or red veiltails. those colours (blue, red) and the veiltail gene (for lack of a better wording) are the most dominant of the b. splendens when it comes to breeding. it gets more complicated once you talk phenotypes (i think thats the word to use), lol.

vacountryboy, do you have room and the resources to care for the potential hundreds of fry you will end up with? that is a major question you have to ask yourself before you even attempt to spawn them. i don't mean to discourage you from the awesomeness of breeding and raising something yourself, but you have to be very critical of the situation and be sure you can do it before you start. i'd start collecting lots of big jars now if you are!
 
allll the males will need separate housing once you sex them; you'll probably have to use jars and do significant water changes every day. Until they get older and develop aggression too, the females will need a growout tank, depending on the spawn maybe as large as 55g
 
the females, if raised together, would most likely be ok in a 'betta sorrority' tank. make sure you have lots of room for them and lots of plants and spots for them to be comfy. but with potentially half the spawn being female, you would need a pretty big tank to keep all the girls long term.
 
I have a bunch of females from the same spawn in one of my tanks, and they are terrors on the brink of war, honestly. As they grow up, they get more aggressive toward each other. :(
 
sessime, are yours full or part crowntail? i've read and had experience that crowntail females (and males) can be rather owly, especially as they reach maturity.

i tried a betta sorrority with three girls that came from the same shop, but at slightly different times and definitely from different spawns, and that didn't work due to aggression. all three were at least part crowntail (pet store 'mutts').
 
They are half crowntail, half halfmoon. (The breeder calls them "Halfsun") I suppose that could be a contributing factor. I kind of wish we could go back and not have gone down that road.
 
i will agree with what yall have said i have 100 of the big size mason jars and a 100 gal pond tub in my basement!!!!!!!!!!!!! im halfway there!!!!!!!!!!!!!
