If you have koi fish in your pond, there’s a distinct possibility you may be right. If you don’t, we may have a mystery on our hands.

For the purposes of identification, koi eggs are about the size of small beads – or small pinheads. Their color can range from milky white to greenish brown, and you’ll often be able to see black dots – which are developing koi eyes – inside them.

Fortunately, by the time you’ve identified the eggs, Mother Nature is already on the job. But, as a good steward to the future koi of America, you might consider adding some Aquatic Plants to the pond to provide good hiding spots for the fry. With everything from floating plants to pond flowers to submerged oxygenating plants, we have plenty of choices to keep your kiddie koi safe from predators – until they’re ready to make it on their own. For an added measure of protection, consider our Koi Shelters, which provide safe havens for koi of all sizes.

Koi eggs generally hatch within a week. So, within a few days from your first sighting, you’ll be graced with an abundance of koi fry. When they’re first hatched, koi fry can’t swim – so they attach themselves to the sides of the pond to grow. Within three or four days, your koi fry will begin to swim.

While it might be tempting to give your fry a welcome feast, there’s no need. During the first stages of their development, your koi will find sufficient natural food in the pond. By the time they’re approximately three to four weeks old, the koi fry should be between ¼” and ½’ long – and they’ll still be capable of finding sufficient natural food in the pond.

After two to three months, your fry will have reached between 2” and 3” in length. They’ll continue to grow until they’re between fifteen and twenty years old – so they’re just getting started. And with an average lifespan of approximately fifty years, you’ll have plenty of time to appreciate your koi, and the generations of offspring they’re sure to produce.

Why do fish swim in schools? | Ponds & Lakes Q&A

Why do fish swim in schools?

Most people are well aware that fish – most of them, anyhow – swim in tightly-knit groups known as schools. But when pressed for a rationale, few people know exactly why fish are so intent on sticking together. As it turns out, school is just as smart for fish as it is for people – but for some very different reasons. So, in no particular order, here they are.

There’s safety in numbers. When pond and lake predators look for a meal, they look for easy targets. And while a school of fish might seem like a logical choice, it’s actually easier to identify a single target – and track it down. Schools of fish, on the other hand, present multiple targets. And when a predator goes in for a snack, the school scatters, making it difficult to keep track of a single individual long enough to catch it.

But when survival’s at stake, group behavior can always use a helping hand. That’s why we recommend Porcupine® Fish Attractor Spheres. When placed in your pond, fish will enjoy improved spawning habitat, and young fish will have a great place to hide when predators are on the hunt. Using our Fish Attractor Spheres, you’ll see improved fish survival rates, healthier stocks, and, if you’re so inclined, better fishing.

The buddy system makes life easier. When a fish goes solo, he faces currents and resistance all alone. And when you have to fight resistance on your own, you have to work hard just to get where you’re going. In schools, however, a lazy fish can draft off the fish around him, significantly reducing resistance. By reducing the energy they need to expend, they can expend even less energy looking for food.

For a good paradigm, think of the Tour de France. During each stage of the race, a few aggressive riders typically break from the tightly-packed peloton. Those lead riders are often overtaken late in the race by riders who stuck with the peloton for the majority of the race to enjoy the benefit of riding behind and among other riders whose bodies reduced wind resistance and made the ride less fatiguing. The breakaway riders, on the other hand, are forced to work harder, making it tougher to maintain the lead. Migratory birds often employ the same tactic, flying in v-formations to reduce drag and conserve energy.

While schooling helps to preserve energy, it’s still important that your fish have the proper food to stay healthy, active, and capable of successful reproduction. We strongly recommend a scientifically-balanced food like Game Fish Grower Fish Food. Designed to promote optimal growth of game fish like bass, bluegill, trout and perch, the large pellets are high in protein, which helps to promote a strong, healthy fish population for more satisfying game fishing.

Having walked our way through fish that do school, it’s worthwhile to note that some simply don’t. In most cases, those fish have evolved with a different set of survival techniques – from hiding to aggression – that works just fine for them.
