      What to Look for in the Best Tank for Guppies

      There are several factors to consider when selecting an aquarium suitable for guppies.  The best tanks will offer you a beautiful viewing opportunity so you can get maximum enjoyment out of your fish. The tank needs to be large enough in order to support all of the fish in it. The main three factors to consider when thinking through a guppy aquarium are materials, price, and quality.

      Material

      The most frequent materials for fish tanks are glass and acrylic.

      Glass is the most popular material for fish tanks. It’s simple to maintain, and it comes in a variety of thicknesses and styles. However, there is a major drawback to using glass aquariums. If it were to fall and shatter, or be bumped too hard, it could easily fracture into small, sharp pieces. The pieces are dangerous in and of themselves and you find yourself with your tank leaking on your floor.

      Acrylic fish tanks are frequently more expensive than glass. Acrylic is lighter and more durable than glass. Acrylic, on the other hand, has three distinct disadvantages. It scratches readily and requires special cleaning solutions. Additionally, it can yellow over time when exposed to UV light, making it more difficult to see your fish.

      Plastic tanks are not as durable or scratch-resistant as glass and acrylic so we recommend avoiding them.

      Price 

      Consider your whole equipment budget, including fish, filters, tanks, aquariums, cleaning materials, and other expenses before purchasing a guppy tank. The aquarium will make up a significant portion of your starting cost.

      The size of the tank needs to reflect how many guppies you plan to keep. Guppies are notorious for reproducing quickly, so it is usually a good idea to buy a little bit bigger tank so you have some extra room. However, the downside of this is that the larger the tank, the more costly the tank and its accessories typically are.

      Quality

      It’s critical to choose a high-quality tank because you want it to last for years. Verify that all parts are compatible and that the product has received favorable reviews from other aquarists.

      You get what you pay for with aquariums. The less expensive options are more likely to have issues. One potential workaround is purchasing a high-quality second-hand aquarium that is in excellent working order rather than a cheap new one. This can be a cost-effective way to get a really nice setup.

      Minimum Tank Size for Guppies

      Guppies are on the smaller end of the freshwater fish scale. They max out at about 2 inches, so they don’t require a huge aquarium. At the absolute minimum, for a small group of guppies (less than five), we recommend 5-gallon tanks.

      However, as with most fish species, if you can go bigger, your fish will appreciate you. And bigger tanks are easier to care for because they’re less likely to experience water parameter fluctuations.

      guppy tank

      If you have five to ten guppies, we recommend a 10-gallon tank. The larger size of this aquarium allows for plenty of growth room so that each fish can live happily and healthily.

      If you plan on keeping more than ten guppies, we recommend a 20-gallon tank or more. The larger size will allow the fish to further spread out and feel less cramped.

      Can You Keep Guppies in a Glass Bowl?

      Easy answer here – no. Fishbowls are not a good choice for any fish. Bowls have a small volume, which means the water becomes dirty quickly and is harder to keep stable. In addition, bowls do not provide your pet with adequate living space as they’re cramped and have restricted abilities to move. Plus, glass bowls don’t have filtration, which is a requirement for clean water.

      Buying a Kit Versus Buying an Empty Tank

      Kits are convenient because they include everything you need, including the tank, light, filter, and pump. Typically, all you need to add is a heater, decorations, and fish to get your aquarium up and running. Kits are a great option for aquarium beginners.

      However, you sacrifice customization with a kit. You may mix and match your own equipment by purchasing an empty aquarium tank. This may be useful when you need to replace certain pieces of equipment and don’t want to replace the entire kit. This is also the way to go if you’re a more experienced aquarist and comfortable with making the equipment decisions by yourself.

      How Many Guppies Can You Keep in a Fish Tank?

      Aquarium overstocking is a common problem among beginners. You want all the species simultaneously and don’t start with a tank that is large enough to support them. When a tank is overstocked, oxygen levels drop and toxins build, which is a bad situation for your tank inhabitants.

      Our recommend rule for guppy stocking is 1 guppy per gallon. Therefore, a 5-gallon tank should have 5 or fewer guppies (ideally 2-3), a 10-gallon tank should have 10 or fewer guppies (ideally 5-6) and so forth.

      Beyond the absolute number of guppy fish, the female to male ratio is important. Guppies enjoy reproducing and will quickly get to the act, leading to a population explosion in your tank.

      The best way to avoid this issue is keeping a 3:1 female to male ratio, keeping only females, or keeping only males. However, the male-only tank can be difficult as your fish will likely get into small skirmishes.

      If you’re dealing with a continual guppy breeding issue, one organic solution is adding a female betta to the tank. She will happily snack on the fry and keep your population levels low.

      Best Tanks for Guppies: Tank Set-up

      Besides the tank, there are a number of other elements to consider when setting up guppy tanks, such as filtration, lighting, decorations, and substrate. Let’s explore each element below.

      Plants in your Guppy Aquarium

      Guppies appreciate when you try to create a natural environment for them, complete with living plants. Plants clean and oxygenate the water. Plants are also natural hiding places for baby guppies so they can grow up in peace.

      Some plant ideas for your goldfish tank include Java FernAmazon Sword Plants, Hornwort, Anubias, and Water Wisteria. However, your guppies will approve of whatever you pick, so don’t stress on it too much!

      Best Tanks for Guppies: Equipment

      Plan your budget before you go shopping. You should also remember that you’re not just buying fish and a tank; there are other pieces of equipment you’ll need!

      Filter

      Sponge Filters are a great choice for guppy tanks. They’re affordable and easy to use. They’re an excellent choice for Guppy and other smaller-sized fish that have low bio-load (waste) outputs. An additional bonus is that the filtration intake suction isn’t super strong, so small fish and fry are less likely to get injured and killed in the intake.

        Substrate

        The substrate is the base layer of your tank. It can be gravel, sand, or bare.

        Guppies appreciate planted tanks, and planted aquariums need substrate to anchor their roots.

        Lots of fishkeepers prefer sand for their guppy tanks. Sand is simple. It has a fine texture that lessens the risk of it getting stuck in your filtration system, or even worse, inside your fish. It is also doesn’t collect excess dirt, food, or waste, so it is a good option for keeping everything clean.

        If you’re not pro-sand, we’d recommend looking into smooth gravel.

        Lighting

        Guppies need light; in a completely dark tank, they will not flourish. Additionally, if you keep your guppies in a planted tanks, you will need to make sure there is sufficient light for strong plant growth. Whatever you do, don’t put your tank in direct sunlight as you’re asking for an algae problem if you go that route.

        We recommend a full spectrum LED lighting system. Check out our best-LED lighting for plants guide for more ideas.

          Heater

          Guppies do best in waters ranging from 72⁰F – 84⁰F. Depending on your local climate and the time of year, you definitely could need a heater to keep your waters in the appropriate range. Check out our aquarium heaters guide for more information.

            Make sure you’re keeping your aquarium at the correct temperature. To do, you’re going to need an aquarium thermometer. Plus, they’re cheap! Our aquarium thermometer guide has all of the details. To further automate your tank, you can add a temperature controller to keep more precise conditions in your tank.

            Testing Kits

            Lastly, water checks on a regular basis (weekly) are recommended to monitor pH, ammonia, nitrites, and nitrates. This will help ensure your tank is clean and the water parameters are steady. There isn’t a test kit for everything, but there are kits that can give you accurate readings. We recommend testing kits by API. Our best aquarium testing kits guide has all of the details if you want to explore your options.

                          Best Tanks for Guppies: FAQs 

                          Can guppies live in a tank without a filter?

                          Although it is not recommended, guppies can survive without a filter provided they are fed properly and all other water conditions are stable. However, you have to keep the water clean by changing at least 50% of the water every day. Because of this, we only recommend this option for experienced aquarists with plenty of time on their hands for water changes.

                          Can I use an air pump in my guppy tank?

                          Absolutely! But make sure you don’t use one that is too powerful, or it might cause the current and surface of the water to become turbulent, which can increase the stress levels of your guppies.

                          Can guppies live in an unheated tank?

                          Yes, guppies can be kept in unheated tanks without much difficulty provided all other conditions are stable and the water temperature isn’t too far off from their ideal range of 72⁰F – 84⁰F. Stability in tank conditions is important for your aquarium guppies’ long-term health.

                          Will guppies overpopulate a tank?

                          Guppies are prolific breeders. This combined with their short gestation period makes them very good at overpopulating a tank quickly. So if you’re thinking of getting guppies for your aquarium, then you’re going to want to think about what to do with the inevitable fry population you will soon experience.

                          Conclusion – What are the best tanks for guppies?

                          All guppy tanks are not created equal, and there is no one perfect tank that will suit every person’s needs.

                          When evaluating the best tanks for guppies, it’s important to consider your budget, the size of your home or apartment, how many fish you plan to keep in the tank, filter requirements, and more. This guide should help point you in an appropriate direction so that finding the best tank for guppies becomes much easier!

                          What is your favorite guppy tank? Are you team glass or acrylic? Do you struggle with guppy overpopulation issues?
