How long can guppies live?

Usually, with proper care, guppies live for between one and two years.

However, as said “with proper care” is the primary part of that sentence.

If you keep your guppy fish in a tank that is too small for them or don’t feed them properly, then they are unlikely to live very long.

It’s not unheard of for guppies to live as long as four or even five years. However, these are exceptions and most guppies will live for between one and two years.

What factors can affect how long guppies live?

There are a number of factors that can affect how long guppies live. These include:

Water quality – guppies living in poor quality water are more vulnerable to disease and less likely to live a long life

Water temperature – guppies living in cooler water will grow more slowly and live longer than guppy fish kept in warmer water

Diet – feeding your guppies a nutritious, varied diet will give them a better chance of living long lives

How Long Is Guppy Maturity? How To Track It?

Once you start tracking your new batch of fry you are going to want to watch closely the sexual maturity of your guppies so you can pick your future breeders.

In most cases, you will find that it takes anywhere from 2 to 4 months for them to mature at the sexual level. There will be many factors that encourage this maturity.

The temperature of the water, as well as the food tank mates and the type of food that you are feeding them, will all be big factors contributing to their maturity.

It has been indicated that the higher the water temperature staying within the acceptable range, is the faster the guppies’ metabolism is functioning.

The consensus is that if you give the proper amount of food for the rate that the guppy is growing at and they can consume it, then the faster the guppy will grow.

Commonly you will just add the food to the guppy tank and let them go about their feeding.

You want to make extra observations here to ensure that the other fish in the tank are not intimidating the younger guppies so that they are afraid to eat.

Tracking Guppy Sexual Maturity

There is a basic timeline that you can follow for the maturity of the guppies.

From the time they are born to about one month, they are considered fry.

Then at the one-month to two months stage, they have reached a juvenile level.

Then provided that the conditions have been perfect in respect to the temperature, water quality, and food, and no intimidation, the guppy should be fully matured by the middle of the third month.

You also have to consider the different genders. Commonly a male guppy is able to reproduce at the one-month stage of age.

So if you have matured females that you are putting in with your one-month-old male then he should be able to do the job of impregnating the females.

It will be different if you are introducing young males to young females, however.

The females do not sexually mature as quickly as the males and it is indicated that the female maturity arises around the three-month period.

Try and differentiate between general maturity and sexual maturity. When you’re looking at the general maturity they are full-grown and have all of their colors around three months.

in Summary

As you may have guessed if you are going to go into the activity of breeding your guppies then there is going to be a demand for a lot of observation on your part.

You really have to be observant as to how your guppies are changing and what all the indicators are that they are going to be prime for breeding based on their sexual maturity both for the male and the female.
