How Do You Take Care Of A Guppy Fish?


Preparing Guppy Fish Aquarium and Care Of Guppy

Although Guppy is a small fish, you may need a bigger tank for them. You would like to keep several Guppy fish in one tank. Otherwise, they would be alone and not nice to see. When there is a group of Guppy fish swimming around, now that is something nice to see.

And there is another concern too. If you keep a small tank (like 5 gallons), it tends to be messy and dirtier more often. And it is very hard to clean small tanks. After considering all these reasons, the minimum size for the Gyppy tank would be 10 gallons. You can choose smaller tanks at your own risk.

The bottom of the tank should fill with at least 2-3 inches of gravel. This gravel layer is important for the filtering of the tank water. You should make enough hiding places for Guppies in your tank. But do not put sharp edge object. These are a very small animal, and they can harm themselves.

The best temperature range for tank water is 23 – 27 0C (75-82 F). in this temperature range, guppies will live up to 2 -3 years.  If your area’s environmental temperature is less than this range, use a heater in one end of the tank.

Make sure to use a thermometer to monitor the temperature of the tank. In low temperatures ( lower than 23 0C), Guppies are grown slowly, and their life span increases up to 3-4 years, but they will be mature later.

If you keep your aquarium temperature around 27-28 0C, Guppies will grow fast and mature earlier, but their life span will decrease to 1.5 years.

Guppy is a hardy fish, and they can tolerate pH from 5.5 to 8.5 in natural environments. But it is ideal for keeping your tank’s pH in the range of 7.0 – 7.2. use a suitable meter to check your tank’s pH level daily.

You can decorate your tank according to your preference.

For show tanks, you can use

  • Use gravel or sand substrate
  • Use a lot of live plants to create a forest-like an appearance. You can use Hornwort, Amazon sward plant.
  • Use round rocks for decoration
  • You can also use dead wood
  • Give some hiding places

For breeding tanks

  • No substrate at all (easy to clean)
  • Only use floating plants like Java moss

Guppy likes typically to swim around in the tank if they try to hide all the time that may be a sign of stress.

Filter setting

The filter system depends on the size of the tank. For a 10 gallon tank, it is enough to use hang on back filter. If your tank is too big (like 50 gallons), you have to use an external canister filter, otherwise, your tank will become dirty so often.

Tank mates for Guppy

You can keep all the guppy tank, and it is an absolutely fantastic sight. You can use different varieties of Guppies for your tank. Ideally, you can keep 1 Guppy in 2 gallons of water. So 10 gallons can hold 5 Guppy without trouble.

Since Guppy is non-aggressive species, you can keep them with Mollies, Gourami, Platies, peaceful tetras, Ghost shrimp and African dwarf frog. But do not overcrowd the tank. Keep in mind species like red-tailed sharks, Barbs and aggressive tetras are not suitable tank mates for Guppy. So keep your Guppy away from them.

Guppy Food and Care Of Guppy

Guppies eat both plants and small animals. Hence they are known as omnivorous. In a natural environment, they have plenty of food, and they can eat anything they want. But in aquariums, you need to feed your Guppies properly.

If you need to keep color Patten of Guppies as it is, you have given them specially designed quality flake food. It will enhance the color of your guppies.

Other than food flakes, you can give freeze-dries food like blood worms and brine shrimp. This will provide your fish a food verity. Also, you can give then live food like algae, but it will deteriorate your tanks’ water quality and, therefore, not recommended.

You can also feed Guppy with a vegetable like peas, lettuce and cucumber.

How often You Should Feed

It is essential to remember Guppies are a small animal, and overfeeding may cause stress. Guppies are food beggars, and with love, you may want to feed them more, but it can be deadly for them. Only feed adult fish once or twice a day and fry 3 to 5 times a day. The amount of food should decide for you. For adult fish, It usually is, the quantity of food a fish can eat within minutes or less. If there are any leftover foods, remove them quickly before giving more food. You should monitor their feeding behavior, which also index of the health of your fish.

Guppy Fish Breeding ?

Of course, we can quickly breed Guppies without trouble, maybe without our interference. You can let them breed in their residence tank, or you can make a special arrangement for breeding guppies.

Guppies are live-bearers, which means Guppy mothers keep their eggs inside their bellies until the egg hatch.

Before go into Guppy breeding, decide whether you are going to keep breeding couples in the same tank or moving to another tank. If you’re going to move them into another tank, make sure all the parameters in the tanks are similar. Otherwise, they will get stressed.

Choosing Couples

If you are going to let nature get it course, you do not have to do anything but keep an eye on them. If you want to do more than sit and watch, you can choose male and female fish by size, tail shape, color or pattern in the body for breeding.

You can put 2 males with one female in a breeding tank. Don’t worry, unlike other species; Guppies are not a shy species. So they will do their job perfectly sooner than later.

After Breeding

Since they are live-bearers, they will give birth to live animals, unlike egg-laying species. When females get pregnant, you can check easily. They will develop a dark spot at the end of the anal fin. That is where female Guppies keep their babies until they born.

If your pregnant Guppy in a resident tank, you can move them now into another tank until babies are born, or you can keep then in the same tank.

When Fry Comes Out

At this time, you may want to keep an eye on your Guppy fries. Guppy mothers sometimes eat their babies after birth. This situation is straightforward to prevent. You only have to provide enough space fry to hide.

If it is your typical tank when decorating, it put some live plants and makes some hiding places. If it is your separate breeding tank, add a breeding trap into your tank.

In the breeding trap, there are two sections, separated by a wall. When mother fish lay eggs, the fry can swim into a breeding trap and safely stay there.

Tank Condition During and After Breeding

Guppies are hardy species but Guppy Care is must. But it is essential to keep good water quality in the tank. Otherwise, the fry will get sick. Keep a good aeration system to circulate the water and oxygenate the system.

Take Care of the Guppy Fry

Fry does not new special temperature changes, but it is better to give them a temperature between 24 – 26 0C.

When feeding them, you have to consider their size. Fries are smaller than adult Guppies. Therefore they need to fed smaller food particles. You can feed them with especially med fry food or crushed larger food pellet. You can give them brine shrimp or blood worm to enhance their nutrient profile.

Keep the tank as clean as possible since they are very small and susceptible to diseases. It is very wise to keep fry separately until they improve their immune system. It will make it easy to keep an eye on these small creatures. You can spot their changes through regular monitoring.

Your fry babies are ready to move into the adult tank after 6 -8 weeks. They will be mature enough to breed around 20 weeks from birth. If you are a commercial fish breeder, keep your notes on these dates.
