b. no more than 3-5 feet of fish length

12. Fish should be introduced to a pond in a plastic bag filled with water because:
a. fish perform best in little greenhouses made of plastic bags
b. they will disappear to the bottom of the pond as soon as you let them go
c. the fish will be stressed by sudden introduction to the pond's different temperature
d. this is no longer a recommended practice

Answers:
1: b - If located in the lowest spot, everything drains into the pond, making it harder to keep it balanced and clean.
2: d - Anything to do with water must be okayed by the Department of Natural Resources since they oversee all drainage issues.
3: b - It's critical to be able to take care of your pond from almost all sides, hopefully without having to get in!
4: a - Deeper is fine, but 18 inches will allow the fish and hardy plants to winter over. Any shallower and the fish will die.
5: c - You must, however, dig the hole to the exact measurements of the liner. Flexible liners give you more flexibility but are a bit more expensive.
6: d - Concrete will last the longest, but you must be on the alert for cracking. Flexible and preformed liners generally give 5-10 years of wear.
7: c - These plants are essential to keeping a pond balanced.
8: b - These plants are anchored in tubs and pots on the bottom or ledges so they can be removed if necessary.
9: a - Tropicals are a beautiful addition, but they do take the extra maintenance of bringing them indoors in winter.
10: d - Algae is a natural part of a balanced pond; you'll never be rid of it all, nor should you try to be. It helps as long as it doesn't get out of hand.
11: a - Putting more fish in a pond than can maintain a balance will stress the fish, destroy plants, and make the pond impossible to balance.
12: c - You want to protect your investment, so acclimate your fish gradually to their new circumstances.

If you guessed 11-12 CORRECT:
You must have algae in your pockets. You love ponds so much, they've grown on you! Congratulations!

8-10 CORRECT:
Consider yourself a pond expert. If you don't already have a pond, one should definitely be in the works this spring.

5-7 CORRECT:
You're on your way, maybe just getting started. Keep reading those books about koi and oxygenating plants and plan a visit to an aquatic garden center this weekend.

1-4 CORRECT:
You are just getting your feet wet where ponds are concerned, but that's great. You are about to enter a whole new world. It's currently one of the hottest and fastest-growing types of gardening.
