While tilapia retails for P80 per kilo, ornamental fish can be sold for as much as P20,000 per kilo. Gram for gram, they eat about the same amount of food. Due to waning stocks, only 10 percent of ornamental freshwater fish are caught in the wild—bold cichlids from the Great African Rift Lakes, striped angelfish from peat-filled Amazonia, and so on.
