Anyone that has had a pond or is near water has probably heard the call of the bull frog. The low call heard that keeps us up at night, is from the male frog during mating season. Soon after, up to 20,000 eggs are laid and tiny tadpoles appear and begin their journey to adulthood.

Tadpoles will begin feeding on algae or other forms of plant life in their area but may also eat eggs or compete for food against other species of frogs if necessary. Since the tadpole stage offers little defense mechanism, many of the tadpoles are not able to survive, though not all are lost as there are a couple ways they are able to escape danger. Coloration makes it easy for them to blend in with surroundings. When you first walk up to the pond you may not notice them right away. At least not until you disturb them and they begin to swim. This movement is defense number two. Their small mass and quick tail allows them to swim hastily away from the opposing threat. If by some chance their tail can’t get out of the way quick enough, have no fear, the tadpole is able to just grow a new one.

As the tadpole continues to growth it will begin to develop eyes, gills, mouth and teeth to continue feeding. After some rapid growth spurts the tadpole can reach up to 6” in length before growing any legs. This process generally takes up to 3 years to complete.

Finally the legs begin to grow. The back legs start first and then the front legs. Now the tadpoles become more mobile, they lose their gills, develop lungs and a hard skeleton. At this point you can see the tadpole begin to take the shape of a frog. The last thing to go is the tail.

The growth process continues as the frog can now feed on insects and other tasty treats that may pass by until the coming spring when they too will join in the spring time calling.

Why do Koi (and Goldfish) Change Color? – Decorative Ponds & Water Gardens Q & A

Why do Koi (and Goldfish) Change Color?

Why do Koi (and Goldfish) Change Color? Colin – Sunbury, OH

You’ve now created the perfect pond habitat and begun to add fish. Multiple trips to the pond store scanning the tank to find just the perfect one to bring home. Some have spots, some red, some orange with black streaks. At least you’ve found the perfect one, black and white pattern with orange freckles on the face. You make your purchase and carefully introduce your new friend to the pond. Everything is going great until one day a few months later you notice that those freckles disappeared and the perfect pattern is changing to white. What happened? Did the fear of the heron turn him white as a ghost? Is there something you did wrong? Luckily, most of the time it’s nothing too serious. Let investigate a few possible causes.

Sun exposure: If you are in a climate where you experience a cold winter and your koi have been hiding out in your pond waiting for spring you may notice your koi are a little lighter in color once the spring time thaw sets in. This is common because koi do not receive a lot of exposure to the sun over the winter months. Once they get back into the routine and the sun begins to shine this color will usually return.

Genetics: Most koi come from parents that were not identical so the same rules apply. Some coloration is dominant and some recessive. This could also change with time the same way your hair color changes. Someone born with red hair may turn blonde or brown as they grow older. This is just a natural part of growing up.

Stress: Stress factors such as predators, parasites, water chemistry or water quality may affect coloration. A quick change in pH due to overwhelming organics or over population would cause a stressful environment which may cause a color change. Be sure to test your water, address water quality issues if necessary or treat the pond with pond salt, pond and fish conditioner or fish disease control. Watch your fish for behavior clues to determine if they are stressed.

Food: What type of food do they eat? Inexpensive bulk food may not contain as many vitamins and nutrients which may affect coloration. This does not necessarily mean the fish are unhealthy but they may not be receiving enough vitamins to support their color. Try feeding them food such as Pond Logic Growth & Color fish food, which supports coloration or even include fruits and vegetables such as oranges. Koi will love the citrus and this could greatly enhance their color.

Once you’ve addressed all these possibilities sit back, relax and enjoy your koi. The color may have changed but their playful personality will still be the same!
