Same here... I wouldn't spend more than 100 on my dream betta, even if for breeding.
I would only pay $100 to breeders I know
. I've had very expensive fish die on me because of unhealthy rearing, they might look perfect in pictures but end up being weak and sickly. The only pair I ever imported cost me over $100, never spawned and died on me rather quickly.
I've always wanted a platinum white but I'm leery about importing another fish and loosing it soon after. PLus, I don't see myself breeding whites... I like the excitement that a pair with colors bring into the fry's.
