It's a fair price for sure, you rarely see double co-dom het clowns around. I'm frankly surprised the male is so much cheaper.
As for what to do.. Yeah if you have the cash to throw down nearly 5 grand on that female, you'd be doing yourself a disservice pairing her with a male that probably wouldn't even fetch $500.
I wouldn't buy that male either unless you were going to pick up some females to pair him with. If you were able to swing it, a visual clown female would pair wonderfully with that male.
You're in the classic position of someone who bought a male before he had a female to go with it. It's hard to be financially optimized in that situation.
