Ok so I’m about to build a 3000 gallon predatory pond. I just want to make sure I can use pond liner with predatory fish. Also what are the specific rules to stocking the pond. I was thinking three silver arows, 2 rtcs, 1 tigershovelnose, a giraffe cat, 4 peacock bass, 3 iridescents, any other ideas or is that too over stocked?
