Changing prices. Virtually none of the prices are listed on the livestock tanks. If you are Asian or if the owner takes a shine to you-eg. good-looking woman who is driving an older car--not late model high-priced vehicle-driving yuppie guy in expensive clothes then you might get a good deal. Does not give same price to blacks or Hispanics or rich whites as he does for white women and Asians. We got 4 friends to ask for the price of a piece of coral over a five day period. The same piece was priced at $25, $35., $40 and $45---with the Asian offered the lowest price and a white guy in a suit and a black guy in designer clothes offered the higher prices.
