Are Fish Pets? Everything You Need To Know About Keeping Fish

Are Fish Pets? Absolutely, fish are pets and can make wonderful companions, bringing beauty and tranquility to your home. At PETS.EDU.VN, we’re dedicated to providing you with the knowledge and resources you need to create a thriving aquatic environment for your finned friends. Let’s dive into the fascinating world of fishkeeping, exploring everything from selecting the right species to maintaining a healthy aquarium, ensuring a rewarding experience for both you and your aquatic companions. With proper care and attention, these aquatic animals can be great pets.

1. What Makes Fish Unique as Pets, and What Are Your Options?

Fish offer a unique pet-owning experience, bringing color, movement, and a sense of calm to any environment. Studies have shown that watching fish can lower stress levels, making them ideal companions for those seeking tranquility. Fish are often suitable pets for people with limited space or allergies to other animals. They come in various shapes, sizes, and colors, with many exhibiting individual personalities. Depending on the number and type of fish you choose, you can select from a variety of tanks of varying shapes and dimensions. Some fish can even thrive outdoors in ponds.

While dog and cat ownership involves selecting from different breeds, fish ownership offers a much wider range of species to choose from. When planning an aquarium, consider your space and time limitations first. Then, familiarize yourself with the characteristics of fish that interest you and can thrive in your environment. This will allow you to design an aquatic community that meets both your desires and the needs of your new pet fish. What one type of fish requires may be unnecessary or even harmful to another. Some fish thrive in communities with other schooling fish, while others are known to be aggressive or semi-aggressive and will harass or injure less confrontational species.

2. What Specific Needs Do Fish Have as Pets?

When considering a home aquarium, remember that a fish’s health is directly related to its watery environment’s health. Maintaining good water quality is vital, whether you’re caring for your first goldfish or balancing a saltwater aquarium with fish and invertebrates. Establishing filtration to remove waste products is crucial. Many fish require a water heater to ensure the proper water temperature or are sensitive to sudden water temperature changes. Even common household fumes and cleaners can impact their water quality. If fish are kept outside in ponds, protect them from predators and environmental extremes that can put their health at risk.

Fish need a balanced diet, clean water, appropriate light, and a suitable environment. Some fish require frozen or live food to stay healthy and happy. Good husbandry is critical to pet health. Seahorses, for example, are beautiful and intriguing fish. However, their dietary needs (typically live food) and exacting water quality needs make them an unwise selection for the novice. Pet fish can also become ill and may benefit from veterinary care.

When stocking an aquarium, consider each fish’s average adult size. Many of the small fish readily available in pet stores or online can grow into large fish and outgrow home systems. A common Plecostomus, for instance, is often seen in aquarium stores, but they can grow to be over twenty inches in length. Numerous excellent books are available to guide the budding home aquarium enthusiast.

Need	Description
Water Quality	Maintain clean, filtered water.
Temperature	Provide appropriate and stable water temperature.
Diet	Offer a balanced diet, which may include live or frozen food.
Environment	Create a suitable habitat with appropriate lighting and decor.
Veterinary Care	Seek professional help if your fish shows signs of illness.

3. Do Fish Fit Your Lifestyle, and Who Will Care for Them When You’re Away?

Keeping fish is a wonderful family activity. Families should involve their children in caring for fish, but youngsters need the help of an adult willing, able, and available to supervise the daily care of fish. Setting up a tank is a creative activity for everyone. For more complicated systems, including saltwater tanks, some people even employ services to care for their system and fish.

Caring for fish is also relatively easy when you travel. Depending on how long you are gone, you may skip a feed day, have an automatic feeder, or have a friend come in to feed your fish. If you are away longer, you will need a friend or a service to come care for the tank (water quality) and feed the fish.

Be aware that homeowner’s associations or landlords may place limitations on the size of the aquarium permitted where you live. You may need additional renter’s or homeowner’s insurance to cover any water damage or losses associated with an aquarium.

Although uncommon, there is a human health risk to consider when keeping fish. Mycobacterial infections can be transmitted by aquarium fish and cause skin infections. The risk of infections is higher for people whose immune systems are not fully functional.

If you find your fish are no longer an appropriate pet for your family, seek help in finding them a new home. Remember, never release a fish into the wild, whether in a neighborhood pond or into a wilderness area or local beach. It’s not good for the animal or the native wildlife.

4. Where Can You Acquire Pet Fish, and How Affordable Are They?

Many freshwater and some saltwater species are bred for the pet trade. More and more fish dealers are working with suppliers that certify that their collection practices have little impact on wild fish habitats and populations. Ask your fish dealer where your fish originated. Fish raised to be pets will likely be healthier and live longer, and their purchase supports sustainable practices. Breeders sell some fish directly, such as koi. If you are interested in koi, you can find a koi show near you to see what fish are available.

The cost, care, and time commitment required for home aquariums vary as much as the individual characteristics such as color, size, and lifespan of fish species. The costs of the equipment to maintain the aquarium is often higher than the cost of the purchase of the fish. First-time home aquarists should avoid species that have complicated requirements. Freshwater systems are generally less expensive and easier to set up and maintain than saltwater ones.

Water quality test kits will help maintain water quality. Depending on the complexity, they can cost up to hundreds of dollars.

Type of Fish	Estimated Cost	Ease of Care
Goldfish	$1- $10	Easy
Betta	$5 – $20	Moderate
Neon Tetra	$2 – $5	Easy
Koi	$20 – $100+	Moderate

5. How Can You Select a Healthy Fish for Your Aquarium?

It is good to visit pet stores a few times to assess the health of animals in general. If you often see sick or dead fish in the tanks, it is probably better to move on and find ones that are more active. Generally, you want a fish that appears to be behaving normally and has its fins spread. It should not be gilling (breathing) abnormally (you can compare the fish you are selecting with the tank mates). There should be no wounds. The eyes should be clear, and it should have a normal body condition with intact skin and fins. Sometimes, you have to look at online references and well-kept home and aquarium specimens to learn what is normal.

Signs of a Healthy Fish:

Active and alert behavior
Clear, bright eyes
Smooth, intact scales
Normal breathing patterns
Healthy appetite

6. What Preparations Are Needed Before Bringing Your New Fish Home?

You should research fish you want to purchase before setting up the tank and getting the fish, since you want to use the correct “furniture” in the tank and know what the ideal temperature and space requirements are. Know the natural history of the species that interest you. With fish, homework upfront can help a family avoid unnecessary and sad losses. It is helpful to identify an aquatic veterinarian or, at a minimum, a veterinarian with some experience with fish, when you are considering obtaining fish.

Taking home a sick fish is never a good idea. Even a healthy fish may be carrying parasites, bacterial, fungal, or viral diseases. For this reason, new fish should be quarantined for at least a month before being introduced to your existing fish. This requires a separate tank setup. Not doing this may expose the fish you already have to diseases that may harm or even kill them. During this month, you should carefully observe the new fish. If they are doing well at the end of the month, there is less risk in introducing the new fish; however, it is never risk-free. If they are not doing well, you should contact your aquatic veterinarian, who is the best person to advise you about health care for your fish.

7. Understanding Fish Behavior: What to Expect

Fish behavior can vary greatly depending on the species. Some fish are social and enjoy being in groups, while others are solitary and prefer to be alone. Some fish are active swimmers, while others spend most of their time hiding. Understanding the natural behavior of your fish is crucial to providing them with a suitable environment.

Schooling: Some fish, like tetras, prefer to live in schools.
Territoriality: Certain species, such as bettas, can be territorial and aggressive towards other fish.
Hiding: Many fish enjoy having places to hide, such as caves or plants.

8. Setting Up Your Aquarium: A Step-by-Step Guide

Finding an aquatic veterinarian:

American Association of Fish Veterinarians: Visit the American Association of Fish Veterinarians website for a list of aquatic veterinarians near you.
Local Veterinarian: Ask your local veterinarian for a referral to an aquatic veterinarian.

18. Understanding the Nitrogen Cycle in Aquariums

The nitrogen cycle is a crucial biological process in aquariums that breaks down harmful waste products into less toxic substances. Here’s a breakdown:

Ammonia Production: Fish waste, uneaten food, and decaying organic matter produce ammonia (NH3), which is highly toxic to fish.
Nitrification: Beneficial bacteria, specifically Nitrosomonas species, convert ammonia into nitrite (NO2-), which is still toxic but less so than ammonia.
Nitrate Conversion: Another group of beneficial bacteria, primarily Nitrobacter species, convert nitrite into nitrate (NO3-), which is much less toxic to fish.
Nitrate Removal: Nitrate can be removed through water changes or absorbed by plants in planted aquariums.

Maintaining a healthy nitrogen cycle is essential for a thriving aquarium. Regular water testing and maintenance are key to ensuring the cycle functions properly.

19. Choosing the Right Filter for Your Aquarium

Selecting the appropriate filter is essential for maintaining water quality. Here’s a comparison of common filter types:

Filter Type	Description	Pros	Cons

Hang-on-Back (HOB)	Filter that hangs on the back of the aquarium.	Easy to install, provides mechanical, chemical, and biological filtration.	Can be noisy, requires regular cleaning.
Canister Filter	External filter with multiple stages of filtration.	High capacity, excellent filtration, quiet operation.	More expensive, requires more complex maintenance.
Undergravel Filter	Filter that uses a plate beneath the gravel to draw water through the substrate.	Inexpensive, provides biological filtration.	Can be difficult to clean, less efficient than other filters.

20. The Importance of Water Testing in Fishkeeping

Regular water testing is crucial for monitoring water parameters and ensuring a healthy environment for your fish. Key parameters to test include:

pH: Measures the acidity or alkalinity of the water. Most freshwater fish thrive in a pH range of 6.5 to 7.5.
Ammonia (NH3): Should be 0 ppm (parts per million) in a cycled aquarium.
Nitrite (NO2-): Should be 0 ppm in a cycled aquarium.
Nitrate (NO3-): Should be kept below 20 ppm through regular water changes.

Test kits are available in liquid and test strip formats. Liquid test kits are generally more accurate.

21. Understanding Fish Compatibility and Aggression

Understanding fish compatibility is crucial for creating a harmonious community aquarium. Consider these factors:

Temperament: Some fish are peaceful, while others are aggressive.
Size: Avoid keeping large fish with much smaller fish, as the larger fish may prey on the smaller ones.
Habitat: Ensure that fish have compatible habitat requirements, such as water temperature and pH.
Swimming Level: Fish occupy different levels of the aquarium (top, middle, bottom). Choose species that utilize different areas to reduce competition.

22. Common Mistakes to Avoid in Fishkeeping

New fishkeepers often make common mistakes that can harm their fish. Here are some to avoid:

Overstocking: Adding too many fish to the aquarium.
Overfeeding: Feeding fish too much food, leading to water quality problems.
Not Cycling the Tank: Adding fish to an uncycled aquarium, resulting in ammonia and nitrite poisoning.
