Firstly, this was a 2 yr old thread!
However i would like to respond to nmonks.
PS. As for ethics, before buying your betta, think about how it was farmed. For a start, cheap, high-protein foods were used. These would be based on things like fish meal and chicken meal. Secondly, what do you think happened to the females in the brood of babies from which your male betta was selected? The market for female bettas is miniscule. Do you think those females were found nice homes somewhere? Nope. They were killed, and if the fish was farmed in Southeast Asia, probably quite brutally. Thirdly, years of inbreeding to produce those long fins has resulted in a fish that can barely swim. Virtually all male bettas spend a life involving zero social contact with their own species, no chance at all to swim about and explore, and no stimulation in the form of other fish or environmental variation. Of all the fish to keep, bettas are amongst the LEAST ethical there are. If McDonalds sold tropical fish, they'd sell bettas.
Before everyone thinks that this is how all betta splendens are treated, I can categorically state that they are not. I agree that the mass producers will feed high protein unnatural food to get the fish as big as possible in the shortest time, and that females are sometimes culled. I can safely speak for the 2 more well known breeders on this site, Modaz and us, that this is NOT how we treat them.
As for the market for females being miniscule, think again. As a breeder and seller of bettas we have had no problems selling our females, in fact we get more enquiries for females than males.
"Fish that can barely swim" - This is why we are very selective in the pairs we spawn. To state what you did is a sweeping statement of all bettas and as such is totally wrong.
In their natural habitat, male bettas lead a solitary lifestyle. Bear in mind that they live in 10's of thousands of gallons of water for the majority of the time. What would you suggest? Keep males with other males and females? We also are very much opposed to the keeping of bettas in "betta vases" and the like. We have even refused to sell to some people who, in our opinion, would not keep them in a manner we would be happy with.
If your looking at ethics, then all fish keeping should be deemed unethical. After all, they are all kept in artificial environments, which, try as you might, will never replicate their natural habitat.
One thing I have noticed recently when browsing ebay, is the amount of new sellers who have imported bettas purely to sell for profit. If you check the sellers previous sales, half the time they haven't sold fish before. They just get them in, stick them in little jars, photo them, and get them up for sale as quick as possible so as not to increase their overheads. Its this type of trade which should be curbed, as along with the major lfs chains, 1000's of bettas are being imported every month from Thailand/Asia.
Just thought some things needed clearing up there
