I buy from BettaAkapes. He's a really nice guy and his fish always arrive looking better then the pictures. I have a Copper male and female from him. You can't go wrong with his fish and if you look at his website he has some males with fin damage he sells for $5 to $8. I've heard good things about Phusit but have to yet buy from him personally.
It's worth looking at his site. Not all his fish are on aquabid. If you plan on buying more then one if you go through his site he gives a discount. I normally buy out the one I want the most and then send him the codes to the others and he will email me back the price with discount.
