my church has as monster koi pond set up (multiple ponds linked with small streams). one of the priest was over for dinner wit the family and i showed him my 'monster' set up and he saw the peacock bass and was amazed.. so he was wonderin if it was possible to keep them in the outdoor pond. we are in houston, texas so it can get a bit chilly sometimes. would pbass be able to handle cooler water temps? one pond is 2-3 ft deep, another 3-4 feet, and the other about 5 ft deep.
