These are one of the most popular fishes for less experienced families starting a saltwater aquarium. Mollies are hardy and are considered to be low maintenance. They do require places to shelter and reproduce. If your aquarium doesn’t already have plants consider adding some to the tank. Plants will mean extra lighting may be needed during the daytime.

This fish will peacefully live in a community setting of a healthy environment for up to five years. Families will enjoy watching the schools of these fish swim, and the beautiful colors that they’ll bring to your family’s aquarium.

Comparison between Different Freshwater Fish Species

The thought of buying a fish to keep as a pet is not only exciting but it can also be intimidating. There are so many freshwater fish species that make great pets.

When buying a fish, you should think about how large they will be as an adult. Some remain small as adults while others can become much larger and you don’t want them to outgrow their tank as adults. The size of the fish you want determines the size of the aquarium you will need. 

You should also look for a fish that requires low maintenance, especially if you’re a beginner. Maintenance entails feeding, cleaning, and susceptibility to illnesses.

It’s also very important to select fish types that don’t mind living with other fish. Some fish are aggressive and prefer living alone, but many others love living in groups.

Cost of Having a Fish

Other than buying a fish, the total cost of keeping a fish depends on the equipment required to set up your aquarium. There are additional miscellaneous costs, and food.  Most people don’t factor in veterinary charges because the cost of a vet visit is often many times greater than the cost of the fish.

Fish are a low maintenance pet compared to other pets, which is why most people prefer having pet fish in their homes.

Here is a table detailing some of the costs you might incur before and after bringing home a finned friend.

ItemCost
Fish$1 – $10
Gravel /decorations$1 – $30
Aquarium10 gallon aquarium $10 – $3030 – 50 gallon aquarium $350 – $580
Aquarium heater$15 – $30
Filters & Air Pumps$70 – $100
Lighting$5 – $30
Feeding$10 – $100 annually
Veterinary chargesFor most fish, zero
Water test kits$50

The initial cost of owning a fish is not terribly expensive and there are many species to choose from in your local pet store. Notably, some exotic fish species can cost more than $100, however these fish are not as common in a family fish tank.

Lighting and heating options for an aquarium are optional because most fish can do without them. However, depending on the specific pet fish you have, you need to adjust temperatures to their particular needs. While the fish don’t require lighting to survive, the light makes the aquarium beautiful for your enjoyment.

If your home is about 74 degrees Fahrenheit, then you don’t have to have water heaters in your aquarium for many types of fish.

The gravel, stones, and other decorations often depend on the fish type, the size of the tank, and your taste in decorations. The cost of decorations varies from person to person.

What is the Ideal Habitat for a FreshWater Fish?

Materials Used

Before buying an aquarium, you’ll need to know what types of fish and how many you want to have. Aquariums are made of either acrylic or glass. Glass aquariums are more common because they are cheaper.  Aquariums made from acrylic are generally higher end for tanks larger than 50 gallons.  Because of the price and size we will not cover them in this article.

Glass aquariums are less expensive, easy to clean and are also scratch resistant. Most families will choose these because of price, but also because it will be big enough for the fish they select.

Size and shape

When buying a fish tank, the rule of thumb is always having a gallon of water for every fish inch. Larger tanks are better than small ones because it gives your fish more space to swim. A larger tank also allows you to make mistakes and have them not be as bad as they would be in a smaller aquarium. Mistakes get diluted more with the extra water in your larger aquarium, and smaller aquariums have less water to dilute the mistakes.

A nice long rectangular fish tank lets your fish move around and lets the water and oxygen circulate.

Substrate

A fish substrate is often composed of gravel, sand, and a variety of stones. Even though the substrate is optional, it adds aesthetic value to your aquarium. Substrates come in all forms of colors and shapes. It’s a good idea to take time and identify a substrate that matches the theme and colors of your aquarium.

Other than the aesthetic value, substrates also act as a medium where healthy bacteria can live and break down nitrogen to release oxygen for your fish. The substrate is also a place where living plants can grow and provide oxygen for your fish.

Some freshwater fish love burrowing at the bottom of the aquarium for safety. By having a substrate that your fish prefer, you give them an extra sense of security.  Sand is the best type of substrate for fish that love burrowing.

If you don’t have a substrate at the bottom of your tank, it could cause a reflection of your fish at the bottom. Some fish types may get frightened by the reflected images.  Gravel is cheap and very common and it creates a more natural bottom to your tank.

The substrate also acts as a laying ground for your fish. The gravel hides their eggs to prevent other fish in the aquarium from eating them until they hatch.  This is really only important if you are interested in having your fish breed.

If you decide to use a gravel substrate, and you want live aquatic plants, then you will want between one and a half to two inches. The deeper substrate gives the plant roots room to take hold otherwise they may not have enough space for the roots.  If you decide to use sand or go without living plants then the substrate only needs to be between one and one and a half inches deep. 

What is the Best Aquarium Size?

Unlike most saltwater pet fish species, freshwater ones are hardy and don’t need big fish tanks. Here is a table showing some of the most common freshwater pet fish and their recommended minimum aquarium size.

FishAquarium size
Goldfish20 gallons
Zebra Danios10 gallons
Betta Fish5 gallons
Neon Tetra10 gallons
Guppies10 gallons
Rainbow Fish30 – 55 gallons depending on subspecies

The bigger the tank size, the better for your pet because they get more space to swim. It’s also easier to manage oxygen absorption in a bigger tank as opposed to a smaller one. If you plan on having more than one fish type in the aquarium, then a bigger tank is extremely important.

Food Preference for Freshwater Fish

Young fish should eat more protein and fewer carbohydrates for fast growth. On the other hand, adult fish have lower metabolism levels and should eat more carbs and fewer proteins.

Overfeeding your fish is a problem because the uneaten food ends up collecting in the substrate as waste. The waste decomposes and deteriorates the water quality in your fish tank.  The more of this decaying matter that builds up, the faster the water quality will drop.

Adult fish should eat once a day at the same time. Younger fish are more active and may require feeding roughly three times a day. Fish that eat vegetables also tend to eat throughout the day because of their small stomachs. If you can place bits of algae or other plants in their tank for them, they can nibble whenever they want.

You can get different food types for your fish from pet stores. Flakes exist in different shapes, colors, and sizes and different fish can detect .

You should also supplement the flakes with frozen or live food for your freshwater fish for proper nutrition and overall health.  You will notice the fish that eat meat will be much more active during feeding if you give them frozen or live food.

Some of the best frozen foods include brine shrimp and it’s also possible to buy living brine shrimp for your pets. Some of the safest live foods also include earthworms, water fleas, mosquito larva, and wingless fruit flies.

Herbivore fish species like the Mollies enjoy fresh vegetables like spinach, dried algae, or frozen kelp. Fish are a lot like  people and enjoy some variety in their diets.  You will keep them more healthy by feeding them different foods from day to day. There are many varieties to choose from with a quick search in your nearby pet stores.

Aggressiveness in Freshwater Fish

Some fish species can become aggressive, especially if living as a group. Experts say that fish become aggressive if they’re trying to protect their offspring or territory or win a mate. Sometimes aggressive behaviors can lead to the death of other fish.

In a small aquarium the fish may not feel like there is enough space and you may see some fish chasing other fish around.  This may become common during feeding times if they feel that there is not enough room for them to feed together.  With a big tank the chances of their aggressive behavior is greatly reduced.

Here are some signs of aggressive behavior in fish.

  • Flaring of fins
  • Chasing
  • Nipping

General Freshwater Fish Care

To support aquatic life, the water in the aquarium requires balancing several different things. It’s very important to use a dechlorinating agent coupled with an aquarium supplement to achieve the best conditions. Chlorinated water isn’t good for your fish and it needs to be neutralized.

The water should be tested for the PH levels at least once a week using the testing kits. The ideal PH for freshwater fish lies between 6.8 and 7.5, depending on the specific fish you have.

The temperatures of the aquarium should also be maintained between 72 °F and 82 °F, again depending on the types of fish you have. Ensure that your fish tank is placed out of direct sunlight, near windows or near vents. Vents circulate air, which could alter temperatures in your tank. A drastic change in water temperatures can quickly kill your fish. The good news is that you can also regulate temperatures in the aquarium using an aquarium heater.

Water changes in your aquarium should be done every week or every other week depending on what fish you have and how many. Depending on a few variables you’ll want to change between 10 to 25% at a time. Changing the water ensures that nitrate levels in the water don’t accumulate to toxic levels.

If you feed your fish algae, you can also expect a buildup of the algae at the bottom or on the sides of the aquarium. Water with algae appears murky, and the glass becomes cloudy.

Algae magnets or a brush can clean out the algae from the aquarium glass. The substrate can be cleaned by using a gravel vacuum that can filter out the debris leaving your gravel intact.

The filtration system in your fish tank should also be well maintained to avoid having the filters get clogged, and not filtering the water. A total clean out for your filters is recommended every 3 months to ensure that they continue to function correctly.

In a nutshell, having an aquarium in the home often reduces stress and helps people relax. Aquariums also add to the aesthetic look of a home. They are a fairly low maintenance way to beautify your home and give you something to watch other than television.

Basic Facts about Freshwater Fish

There are about 10,000 freshwater fish species in the world and about 800 species in North America alone.

Pet fish are also intelligent and can remember things, regardless of what the myths may tell you. Goldfish often rub against other fish in the tank as a sign of showing affection.

Fish species also communicate with each other through low-frequency sounds. Experts also say that fish are known to cooperate and live harmoniously in groups.
