How to Set Up a Guppy Fish Tank (Starter Guide)

beautiful guppy fish

Setting up an aquarium for guppies is not as complicated as it seems! Keep on reading to find out all the essentials for a healthy and thriving guppy tank.

#1 Choose the right tank size

Generally speaking, guppies do best in tanks that provide 2 gallons of water per guppy, with a minimum tank size for two guppies being 5 gallons.

This will provide them with plenty of space to school, swim freely and keep their waste levels low. When thinking about picking the correct sized tank for guppies, it’s important to also consider adding other fish that fit into the same tank.

Tank SizeGuppiesReasoning
5 gallon tank2-3 guppiesWhile a 5 gallon tank can house a small number of guppies, it’s important to keep in mind that overstocking can lead to poor water quality and health issues for the fish. A 1:2 male-to-female ratio (1 male and 1-2 females) can be maintained in a 5 gallon tank with frequent water changes and maintenance.
10 gallon tank5-7 guppiesMale guppies are generally smaller than females and can become more aggressive if there are too many males in a tank. Keeping a male-to-female ratio of 1:2 can help prevent aggression and ensure a more balanced and peaceful tank. In a 10 gallon tank, 5-7 guppies (2-3 males and 3-4 females) can be comfortably housed with good filtration and maintenance.
20 gallon tank10-14 guppiesA 20 gallon tank provides ample swimming space and room for plants and decorations. A 1:2 male-to-female ratio (4-6 males and 6-8 females) can be maintained in a 20 gallon tank with good filtration and maintenance. However, it’s important to avoid overstocking, as this can lead to aggression and stress among the fish.

Please note that these are general guidelines and there are many factors that can affect the number of fish a tank can support, such as the efficiency of the filtration system, the presence of live plants, and the amount of waste the fish produce.

💡 Guppies can happily live with other small species such as tetras and rasboras as long as there is enough room for all of them.

EpicFishTank Note:

It’s also important to consider the behavior of the fish species being kept and avoid overstocking the guppies tank, which can lead to aggression, stress, and health problems for the fish.

#2 Select the right filtration system

If you’re a beginner looking for a filtration system for your guppies, consider a sponge filter. Sponge filters are a popular choice among guppy owners because they are simple to set up and maintain, cost-effective, and efficient in filtering waste.

Sponge filters are particularly suitable for guppies and guppy fry because they provide gentle water movement and create a calm environment, which is ideal for guppies.

💡 The gentle flow from a sponge filter ensures that your guppies won’t be swept away by the current, which can cause stress or even injury. In addition, the sponge filter creates a surface area for beneficial bacteria to grow, which helps break down waste and maintain water quality.

Another benefit of a sponge filter is that it’s suitable for a wide range of tank sizes and can handle large populations of guppies. This makes it an ideal option for beginners who are starting with a smaller tank and a smaller number of guppies but plan to expand their collection in the future.

Sponge filters are also easy to clean and maintain. You can simply remove the sponge and rinse it under running water, squeezing it gently to remove any debris. This should be done every few weeks or as needed to maintain optimal performance.

Here is a table of the benefits of a sponge filter compared to other types of filters for guppies:

BenefitSponge FilterHang-On-Back (HOB) FilterCanister Filter

Guppy FrySafe for guppy fry, won’t suck them upMay suck up guppy fryMay suck up guppy fry
EpicFishTank Note:

Filtration creates a smooth flow of water in the guppy’s tank. It helps guppies become more active and encourage them to swim around while keeping their delicate fins and tails perfectly flutter.

The Benefits of Sponge Filters for Supporting the Nitrogen Cycle in Guppy Tanks

The Nitrogen Cycle Diagram in Aquariums

💡 The nitrogen cycle is the process by which beneficial bacteria in your tank convert harmful ammonia, which is produced by fish waste and uneaten food, into less harmful compounds like nitrites and nitrates. These compounds can then be removed through regular water changes. Read the explanation of nitrogen cycle process here.

Sponge filters are ideal for the nitrogen cycle because they provide a large surface area for beneficial bacteria to grow and thrive. These bacteria colonize the sponge and consume the waste produced by your guppies, helping to maintain optimal water quality and prevent harmful spikes in ammonia levels.

In addition, sponge filters provide gentle water movement, which helps to distribute oxygen and nutrients throughout the tank, promoting the growth of healthy bacteria and a healthy aquatic environment for your guppies.

Overall, a sponge filter is an excellent choice for maintaining the nitrogen cycle in your aquarium and ensuring a healthy and stable environment for your guppies.

EpicFishTank Note:

As a beginner, it’s important to understand the role of the nitrogen cycle in your tank and choose a filtration system, such as a sponge filter, that supports this essential process.

  3. Gradually add water: Over the course of the next 30 minutes, gradually add small amounts of water from the new tank to the bag. This will help your guppies adjust to the new water parameters.
  4. Release your guppies: After the acclimation period, gently release your guppies into the new tank. Avoid pouring the water from the bag into the new tank as this can transfer harmful bacteria and parasites.
  5. Observe your guppies: Watch your guppies for the first few hours after introduction to the new tank to ensure that they are swimming and behaving normally. Look for any signs of stress or disease, such as hiding, clamped fins, or abnormal swimming patterns.
  6. Feed your guppies: Offer your guppies a small amount of food a few hours after introduction to the new tank. This will help them settle in and adjust to their new surroundings.

💡 Remember to be patient and observe your fish closely to ensure that they are healthy and happy in their new environment.

EpicFishTank Note:

When introducing guppies to a new tank, they may experience stress due to the unfamiliar environment and changes in water chemistry. Stress is a common response in fish when they are exposed to new or challenging situations.

Stress can have a significant impact on the health and well-being of guppies, causing symptoms such as decreased appetite, lethargy, and increased aggression towards other fish. In addition, stress can weaken their immune system, making them more susceptible to diseases and infections.

Guide to Choosing Food for Your Adult Guppy Fish and Guppy Fry

When choosing food for adult guppy fish and guppy fry, it is essential to provide a balanced diet that meets their nutritional requirements. A diverse and well-balanced diet will ensure your guppies’ optimal health, growth, and coloration.

The ideal diet should consist of a mix of high-quality commercial flake or pellet food, live food, and occasional vegetables or blanched greens. The commercial food should be rich in protein (around 40-60% for adults and 50-70% for fry), vitamins, and minerals to support their growth and immune system.

EpicFishTank Note:

Incorporating live food, such as moina and daphnia will provide additional nutrients and stimulate natural feeding behavior.

Table: Nutritional Requirements for Adult Guppy Fish and Guppy Fry

NutrientAdult Guppy FishGuppy Fry
Protein40-60%50-70%
Fat10-20%15-25%
Fiber2-5%2-5%
Vitamins & MineralsAdequate amountsAdequate amounts
Live Food (Moina, Daphnia, etc.)RegularlyRegularly

💡 For adult guppy fish

Adult guppy fish particularly benefit from moina as a live food source because these small water fleas are rich in essential nutrients such as proteins, fats, and vitamins.

Moina also provides an excellent source of carotenoids, which enhance the guppies’ coloration, making them more vibrant and attractive. The natural hunting behavior exhibited by adult guppies when feeding on moina stimulates their instincts and keeps them active and engaged, contributing to their overall well-being.

EpicFishTank Note:

Avoid overfeeding: Guppies have small stomachs and can easily become overfed, which can lead to health issues. Feed them small amounts of food two to three times per day, and remove any uneaten food after five minutes.

💡 For guppy fry

Guppy fry require daphnia as part of their diet to meet their nutritional needs during their rapid growth phase. Daphnia are small, freshwater crustaceans that are easily digestible and high in protein, which supports the fry’s development and growth.

Moreover, daphnia contain essential fatty acids, such as EPA and DHA, crucial for the development of the nervous system and overall health. As guppy fry have small mouths, daphnia’s size makes them an ideal live food choice, encouraging natural feeding behavior and promoting a healthy appetite.

EpicFishTank Note:

1. Gradually introduce other foods: As the fry grow, gradually introduce other types of food, such as finely crushed flakes and live or frozen daphnia.

2. Feed small amounts frequently: Guppy fry have small stomachs and need to eat frequently throughout the day, so consider feeding them small amounts of food four to six times per day.

3. Remove uneaten food: Like adult guppies, guppy fry can easily become overfed, so remove any uneaten food after five minutes to prevent leftover food from polluting the water.

Final Words

After learning about guppies, you should now have the basic knowledge to keep them healthy and happy. Keeping guppies is not difficult and can be rewarding for both experienced and novice hobbyists alike.

It’s important to remember that each tank will have its own unique conditions, so research the species further before adding them to your aquarium. Guppies require hard water pH levels and plenty of areas for hiding within their tanks.

Be sure to provide plenty of plants and other decorations to create more complex swimming spaces. Additionally, it’s best to keep only compatible fish together in the same tank; this way, even timid guppies can adjust comfortably.

With proper research and careful planning, you’ll have a thriving tank of beautiful guppies in no time!
