Pregnant Guppy Fish Care

When it comes to choosing a mate, female guppies often go for the mates with the flashiest, most interesting color patterns. In a new study, Florida State University researchers found that these tiny, tropical fish often choose a mate that physically stands out from the rest of the pack because of a common type of learning called habituation.

Through habituation, animals -- in this case guppies -- stop responding to a stimulus after prolonged exposure. In other words, the female guppy is often immune to the charms of a male guppy that looks like all the other male guppies. Ones with unusual color patterns stand a better chance at successfully wooing a mate. We've shown that this attraction to the unusual happens because of habituation, which means that females tune out repetitive information, and pay more attention to things that look different.

The team's research builds on a study Hughes conducted several years ago that found that guppies' color patterns did seem to influence mate choice. When Daniel came to work in Hughes' lab, he wanted to explore the psychological theory of habituation and whether that explained how female guppies choose mates. That's been a tough nut to crack.

Researchers exposed female guppies to a large number of males with the same color patterns and tracked their responses to male courtship displays. In guppy courtship, the male guppy performs a type of dance around the female to express his interest. If the female wants to participate in this courtship ritual, she will respond to the approach and move toward the male.

Then, researchers exposed the same female guppies to male guppies with widely different color patterns to investigate the response.

In some cases, they held the group of female guppies in isolation for a short period of time. The researchers found that females typically preferred the novel male guppies. But, they also found that male guppies with familiar patterns became interesting again to the guppies held in isolation. Through these experiments, researchers showed that this choice met four criteria that indicate habituation.

Here are some of the important things to know about caring for pregnant guppies.

Guppies are beautiful, interesting fish. They are one of the few species of fish that reproduce by internal fertilization, rather than the males just fertilizing the eggs.

If you have an aquarium , you might have to deal with newly hatched fish at some point. There are a few scenarios in which you may find yourself unexpectedly playing host to quite a few new fishy residents; some fish will breed with your existing fish when introduced to your tank after purchase, while others may already be pregnant upon purchase. It can often be difficult to identify when a fish is pregnant, and depending on her breed your fish can give birth to anywhere from a dozen to a couple hundred fray at once. Some aquarium fish carry the eggs inside of them. When the eggs are fertilized, they eventually hatch inside the mother, and the babies emerge in a live birth. Other types of fish lay hundreds of eggs in nests within the aquarium, in this case, the males fertilize these eggs, and then they hatch into live fish. You may not notice that any of this is happening until you see hundreds of tiny fish swimming around in your aquarium. By that point, is it too late to raise the little guys?

Temperature and light are important. The optimum temperature for fastest development of the brood inside of a female is between 77 F and 80 F and development will take approximately 4 weeks in the average live-bearer. At 68 F, the interval lengthens to some 35 days or more. The female has a normal-shaped anal fin.

Pregnancy has been traditionally defined as the period of time eggs are incubated in the body after egg-sperm union. In ovoviviparity , there is internal fertilization and the young are born live but there is no placental connection or significant trophic feeding interaction; the mother's body maintains gas exchange but the unborn young are nourished by egg yolk.

Having worked with fish most of my life, I have a strong desire to help others to be successful in the hobby. Although it's not possible for a female guppy to get pregnant without a male, it can appear that she did. Research has shown that a female guppy can hold a male guppy's sperm for 10 months or possibly longer. This may give the appearance that a female guppy is pregnant without being in the presence of a male.
