ONE PHENOMENA WE RUN INTO is people with, what we call, "Fish Fear". This occurs with the new pond owner who's afraid that somehow they're going to harm their fish. You know, things like...

They'll freeze over the winter (a winterization).

Or, the pond will spring a leak (a maintenance problem), run out of water, all while they're away at work, land locking and eventually killing their fish.

Or, they'll forget to feed their fish one day (a feeding problem) and suddenly they're on the brink of extinction.

The problem with fish fear is that fish are one of the 5 absolutely necessary, unequivocally required, parts of the balanced ecosystem recipe. Without the fish you're only 0% complete. Without fish you can't have a balanced ecosystem - which is the reason you chose an Aquascape water feature in the first place. And without fish, you'll be missing out on at least 20% of the fun.
