Welcome to mini-pondville, Bobby. You can absolutely have a pond smaller than 1/4 acre and put fish into a pond this size as well.

Subscribe to PondBoss. It is full of great information and helps to fund this forum, where you will find great advice and even better friends.
Figure out your goals first, and then many of the answers and advice will filter in. Do you want to swim in it, fish it, both or neither. Post your goals here along with an idea of what you have done so far. I am told that a small pond will struggle to grow monster fish, but I may try to challenge that theory once I get more of the fun landscaping done. What type of soil do you have?
