Koi & Goldfish

Beginning May 1st (or earlier if the weather allows), we stock our outdoor fish tanks with a rainbow of koi and goldfish of several different sizes and varieties.  These high-quality fish are beautiful, vibrant, and friendly.  If you’re looking for something specific, we will special order for you!

Did you know?

A good rule of thumb when adding fish to your pond…keep in mind your pond size. 

Generally speaking, keep your fish load to 1” of fish for every 10 gallons of pond water.  There IS such a thing as having too many fish!  For example, if you have a 1000 gallon pond, try not to let your fish load be more than 100” of fish.  That gives you about ten koi or goldfish at 10” each.  Having more than this will increase the ammonia in your pond, and also the amount of maintenance you will have to perform due to the added fish waste. 

How to calculate pond water volume:

Keeping it simple, some guidelines:

  • Square or Rectangle: Length X Width X Average Depth X 7.48 = Gallons
  • Circle: 3.14 x Radius X Radius X Average Depth X 7.48 = Gallons
  • Irregular Shape: Average Length X Average Width X Average Depth X 7.48 = Gallons

For irregularly shaped ponds, you can also divide the pond up into sections.  For example, a kidney-shaped pond could resemble two circles pushed together.  Make the calculations and add them up to arrive at the total number of gallons of water in the pond.

**It is best to err on the low side so that you do not over-treat the body of water.
