I would go to cypos.com. There is alot of stock available right now, i just bought some tanz fry. I noticed some colonies for sale, some were wild i think.Several listings for adult fish.
For your cc problem, could you do a cash advance then mail them a money order or cashier check ? or what about those checks your credit card sends you to pay off balences and buy big ticket items, got any around? That might work.
