Koi are the most popular choice of fish for backyard ponds
today; however, there are several other types of fish that
are also used for this purpose. Among these are goldfish,
golden orfe, mosquito fish, bitterlings, mollies, minnows,
game fish, trout and catfish.
- Goldfish are the easiest fish to keep in a backyard
pond and, as a member of the carp family, they can vary
in color from light yellow to red. Their diet consists
of mosquito larvae and most varieties of goldfish do not
outgrow the pond they reside in. Goldfish also breed easily
and the fry are generally black in color and turn gold
if the conditions are right. Types of goldfish, such as
the shubunkin and the comet, have elegant flowing fins
and vary in colors and patterns. In water gardens that
are well planted, these fish may be able to survive without
additional feeding. As a general rule for stocking goldfish,
please allow 10 gallons for each fish.
- Golden Orfes require plenty of oxygen and should not
be placed in smaller ponds or ponds without pumps. They
are bottom feeding scavengers that can share a pond with
koi or goldfish. Golden orfes often put koi and goldfish
at ease while encouraging them to spend more time near
the surface of the pond. Golden orfes are quick and playful
and grow to be around 1.5 feet long.
- Mosquito Fish are excellent in controlling mosquitoes
in your backyard pond. Being in the same family as the
common guppy, the mosquito fish has a long, pale slender
body with a tail that is moderate in size without coloration.
These fish require a pond that is at least 20 gallons
with plenty of plants so they can hide. Mosquito fish
can also tolerate cold weather as long is the pond is
deep enough and if it is aerated through the wintertime.
The diet of these fish consists of the larvae of mosquitoes
and other insects. You may have to supplement their diet
with quality flake food if the amount if natural food
is insufficient. If left to fend for themselves without
a breeding box, the adult mosquito fish may also eat their
own fry.
