Buyer's Guide

When it comes to finding an aquarium for your home, it’s not as simple as picking out any fish tank and bringing it back to your house. There’s a lot to think about when it comes to setting up your fish tank and buying the right aquarium is the first step. For example, when looking at 30 gallon fish tanks, you need to think about the type of fish you want, how much you’re willing to spend, and the placement of the aquarium inside your home.

Species of fish

A general rule of thumb is to have at least one gallon of water per inch of fish plus wiggle room for your fish. For example, a Neon Tetra can grow to be about one-inch long. However, they’re schooling fish and it’s recommended to have at least five in a school. This means there are about five inches of fish in your tank. Double that to get some extra room for your fish to stretch their fins and you should get at least a 10 gallon tank. Before you decide to buy an aquarium, be sure to research the species of fish you’d like to take care of. Some fish are freshwater while others are saltwater. Not every species will get along with one another. Some fish are loners while others are schooling species. A 30 gallon fish tank is a great size but it will limit the amount and type of fish you can get for it. So, if you decide you want to buy a 30 gallon aquarium, be sure to research the species of fish you can get so they can live long, healthy, comfortable lives.

Cost

Keeping an aquarium is fun and relaxing. However, they do require a lot to maintain and the cost can add up. Between the tank itself, the filter and cartridges (depending on the type of filter you buy), gravel, decor, fish food, a net, water treatment, thermometer, heater, and so much more. You may not necessarily need all of this (or not right away at least) but they may be good to have handy anyway. Overall, be sure to create a budget and make sure you can afford everything before you begin buying the equipment.

What equipment do I need?

Aquariums need a lot of equipment to initially get started. First, there are certain items you need to get the tank up and running before you decide to get fish. For this, you need a hood or lid for the tank (if the one you buy doesn’t come with one). This is so the water won’t evaporate as quickly and the fish won’t be able to jump out of the tank. You also need lights. Any sort of light will do, though LEDs are the most popular. They’re energy-efficient and last much longer. Plus, they’re bright and bring out the colors in the decor and gravel within the tank. Finally, you need a filter (more information on that is below). Also, before you add fish, you’ll need gravel and decor. Some other items you may need (but not necessarily right away) are a net to transport fish, a heater, and a thermometer to check the water temperature. Also, a hose, gravel vacuum, and water treatment is a great idea for easy and efficient water changes.

When can I add new fish?

When you first get your new tank, make sure it’s completely set up and you have everything you need. Once you have all the equipment, be sure to set up the tank with the correct amount of water, keep an eye on the temperature, decorate the tank with gravel and other decor, and turn the filter on. Let the filter run for about 24-48 hours so that some bacteria can begin to form within the tank. Some good bacteria live within the water that the fish need to maintain a healthy lifestyle. After a day or two, you can go to the pet store and buy fish for your tank. Also, if you fill up your aquarium with tap water, be sure to add some water conditioner. Then let the filter run for a day or two will get any unwanted chlorine out of the water. A good rule of thumb is to add three fish into your tank at a time whether the tank is empty or you already have fish in there and you add more. This is to ensure the fish get along well as well as get used to their environment. After adding new fish, give them about a week to get settled into their new home before going back to the store to buy more fish.

How often should I clean my aquarium?

A general rule is to clean at least 10% of your tank’s water once every two weeks. You can do so every week but can get away with cleaning it once every two weeks. Once a month, you can do a bigger water change. If you notice your water is getting visibly dirty, then cleaning the water as soon as you can is a good idea. When cleaning, there are a few things you should look out for. Vacuum the gravel so that you may catch any extra debris (such as uneaten food) that didn’t make it to the filter. By doing so, this will also suck out some water so you can do both at the same time. Also, make sure your filter is working properly. If you have a power filter, be sure to rinse out the cartridges or squeeze out the sponge if you have a sponge filter. Or, if need be, replace the sponge or cartridge if it’s visibly dirty and getting old. You should change out your filter at least once every three to six months, depending on the type of filter you have and how strong it is. Finally, you don’t need to take out your fish when cleaning your aquarium. If you have a gravel vacuum, there is usually a small grate at the top so that water and other debris can pass through, but fish can’t. Sometimes a fish may get curious and get sucked up into the vacuum but they won’t be harmed. On the other hand, if you have smaller fish or fry inside your tank, it might be a good idea to scoop them out with the net just to be on the safe side. When you’re done cleaning your tank, if you fill it back up with tap water, be sure to add some water treatment to it. This may be a bacteria supplement or water conditioner. This will help filter out the chlorine from the tap water making it safer and healthier for your fish community.

How do I know what decor to get for my fish tank?

Aquariums need a few things to make your fish feel more at home. First and foremost, you need gravel. Gravel acts as the flooring of your fish tank and will give good bacteria a place to cling to as well as bury waste, uneaten food, and other debris. It’s a good idea to have about an inch or two of gravel covering the floor of your tank. If you have plants and other decor, an extra inch might be needed so the base of your decor can be buried ensuring they stay in place. Additionally, plants are needed in a fish tank for decor. You can get fake plants or real plants. Real plants will help with filtration while fake plants look pretty. Most fish species like to have a place to hide. So, getting plants - real or fake, short or tall - is great for your fish to have multiple places to hide and chill out. You can get other decor such as rocks or sunken ships. These can also allow your fish a place to hide or they can simply be for looks. There are other ornaments you can add to your fish tank such as cartoon characters just to give your aquarium a little more personality. Ultimately, you can add whatever kind of decor you want.

Expert tip

When choosing a fish tank, be sure to take a look at the material it’s made from. Most fish tanks are made from glass but some are plastic or acrylic. Acrylic is great because it’s more durable than glass and plastic.
