We’re currently making a fish and frog pond (and by "we" I mean Julian is working on it). It will
house an array of water plants, tadpoles, frogs and fish that won't need fancy air
filtration devices... It’ll be our little mock Koi poind. Right now
the pond is filled with Sarasa Comets. Comets are the most common variety
of fancy gold fish in the US. In optimum conditions they can grow tails
up to 12” in length! These goldfish are easily recognizable by their long
flowing fins and their red and white coloration which is very similar to that
of Koi’s. They’re quite beautiful and I’m amazed that many of these are
sold as simple “feeder” goldfish (gold fish sold as bait for predator fishes or
for fishing bait). I’ve been rescuing quite a few of them since they
normally have short lives between their overcrowded tanks and being sold as
feeders.
Building of the Frog pond:

About plants:
Plants should cover about 50-70%
of the pond surface. Algae is
also super important for tadpoles meals. When you first set up your pond you
may experience a lot of algae, resist the temptations to clean it out. It
is a natural phase for the pond. Once the nutrients in the pond become
balanced, the algae will reach an acceptable level appropriate for the plants
and animals present. Algae thrive on light and excessive nutrients. To
decrease light you can add more plants, and the algae will compete for the
nutrients and become less pervasive.
All ponds need time to develop
into good amphibian habitat. The quality of the habitat improves when plants
and algae are established, and when decomposed plant and animal matter has
settled to the bottom, forming a source of nutrients for tadpoles and aquatic
life. Plants provide sources of food and
shelter for a large number of animal species. Plants must suit the soil type,
water levels, and the amount of available sunlight.
A pond with lots of hiding and feeding cover
will attract frogs and keep tadpoles safe from fish.
Let the pond sit for a
few days before adding plants. This allows chlorine to evaporate from the
water. Chemicals are also available that will quickly neutralize chlorine and
other harmful compounds.
For the pond, consider a mix of emergent, submergent, and
floating species. Emergent plants, those that have their roots in the water but
their shoots above water, can be added to the margins of pools. Some examples
are cattails (Typha spp.), arrowhead (Sagittaria spp.), and water lilies
(Nymphaea spp.). Submergent species, or those that remain underwater, are often
used as oxygenators. These are plants that remove carbon dioxide from the water
and add oxygen. These plants are essential in most ponds to keep the water
clear. Floating species or those that are not anchored at all in the pond
include plants such as duckweed (Lemna minor), water lettuce (Pistia
stratiotes), and water hyacinth (Eichhornia crassipes). While attractive, water
hyacinth and water lettuce can be serious weed problems in the South. Since
they are not winter hardy, there is no problem with them spreading in northern
climates. While not as effective as oxygenators, these plants help keep the
water clear by limiting the amount of sunlight that algae receive
Place the plants at various depths. Emergent and submergent
plants should be planted into pots. Fill the container about half full with a
mixture of good garden topsoil. Do not use potting mixes or peat moss. These
are too light and will float out of the pot. Place the plant on top of the soil
and fill the container with topsoil within one inch of the top.
When planting water lily rhizomes, make a mound of soil in the
middle of the pot. Place the rhizome at a 45 degree angle. The crown of the
rhizome should be toward the center of the pot. Cover the roots with soil, but
not the crown.
In all cases, add a layer of gravel to the top of the pot. This
will help keep the soil from floating out and prevent fish from digging in the
soil. Slowly place the pots in the pool to keep soil from floating out. Place
pots on bricks to get the desired height. Floating species can be placed
directly into the pond with no other care needed. Plants should cover 50 to 70
percent of the water surface.
About breeding:
Pond-breeding amphibians
are particular about where they lay their eggs. Those that lay their eggs in
wetlands need very slow-moving or stagnant water, and a water level that
doesn’t drop much during the spring breeding season (February through May).
These amphibians need shallow areas between 1/2 foot and 3 feet deep. They
usually attach their egg masses to or among plants, so they need small plants
with thin, flexible stems between 1-4 mm in diameter.
Even amphibians that lay eggs in ponds live part of their adult
life on dry land. For this, their habitat should include trees and shrubs for
protection from predators. They also need leaves and fallen logs to hide in
during cold weather. Protected corridors connected to other wetlands prevent
too much inbreeding, and provide pathways for new amphibians to recolonize in
case a drought, flood, water quality problem, or some other stochastic event
wipes out a local population.

There needs to be enough bacteria and algae on
rocks and the bottom to feed tadpoles, and sufficient aquatic insect production
to feed the adult frogs or toads.
Attract Frogs with
Surrounding Pond Habitat
To improve the area around the pond, place native emergent
plants around the edge to provide cover for adults and emerging toadlets and
froglets. Trees should be planted some distance from the edge of the pond,
because excessive shading reduces wildlife diversity and productivity. Any dead
timber should be left standing or can be added to provides habitat for species
such as beetles and woodpeckers.
A few rock piles and logs arranged around the pond will provide
shelter and refuges from predators. You can provide moisture by having shady
areas where dew collects, moist patches of soil, and rotting vegetation. Rocky
retreats for toads can be made by placing stones to form a rocky burrow about 4
inches high with a sandy floor where toads can dig. You can use pieces of
broken concrete blocks to allow access to the toad chamber and plant ferns to
shade the area.
Some nurseries now sell toad
shelters
, or you can make one yourself out
of a large clay flower pot. Simply drill a series of holes for a toad size
opening, and chip out the drilled section with a hammer. Place one or two of
these upturned flower pots in shady locations in your garden. Adding a toad
lightbetween the rock garden and a lawn
area will attract insects for the toads.
Provide
Extra Shelter. Place a couple of
clay plant pots, on their side and partly buried, to provide extra shelter and
shade. Remember frogs like it damp and cool, and also need places to hide from
predators.
