How much does a pet fish cost? A comprehensive guide

If you're considering adding a new pet to your family, a fish might be a great option. They are relatively low-maintenance, calming to watch, and can help teach your kids about responsibility. However, it's important to understand the costs involved. So, how much does a pet fish cost? Let's break it down.

Initial costs: Buying your fish and equipment

The first step to owning a pet fish is buying the actual fish. The cost of a pet fish can vary greatly depending on the type, size, and rarity of the fish. On average, you can expect to pay anywhere from $2 for a small common goldfish to hundreds or even thousands of dollars for exotic species like koi or rare tropical fish.

Understanding the types of pet fish

The price of the fish itself can vary greatly depending on the species. Common species like goldfish might only set you back a few dollars, while it can go over $1,000 for exotics. The type of fish also determines the cost of equipment. Saltwater fish, for example, require a much more expensive tank setup compared to freshwater fish.

Initial setup costs: Maintaining a pet fish environment

Tank essentials

The initial setup involves various expenses: tanks, filters, heaters, and decorations, potentially totaling $100 to $500+. Quality equipment is essential for the well-being of your fish.

Tank size is an important factor in the total cost. Certain freshwater species, like goldfish or bettas, can thrive in smaller tanks (5-10 gallons). Others require larger tanks (20+ gallons) and more expensive equipment.

Tank accessories such as plants, rocks, and caves can also add to the initial cost.

The importance of water quality

Some fish need specific water conditions that may require a water testing kit or treatment products. These costs can add up quickly and should be factored in when considering the overall cost of owning a pet fish. Invest in water testing kits ($15-$40) and conditioners ($5-$20) for optimal water quality.

Ongoing costs: Food, filtration, and potential vet expenses

Ongoing care and maintenance expenses

Ongoing costs include monthly feeding ($5 to $15) and maintenance ($10 to $30). Equipment operation may add $5 to $20 to your utility bills.

Healthcare and unexpected costs in fishkeeping

Budget $10 to $50 for common health issues, with a reserve fund of $50-$100 for emergencies that require a trip to the vet.

Energy consumption and cost

Operating a tank can add $5 to $20 monthly on your electricity bill. 

DIY vs. professional tank maintenance

DIY maintenance can be more cost-effective than professional services ($50-$200 per session).

Feeding your fish: Types and costs

Fish feeding varies by diet, ranging from $5 to $20 monthly.  Food expenses typically depend on the type of fish, size, and dietary needs.

Reducing costs in fishkeeping

Smart shopping tips for fish and equipment

Smart shopping can make a significant difference in the overall cost of owning a pet fish. Look for sales, discounts, and seasonal deals on both fish and equipment. 

DIY solutions for tank accessories and decorations

Instead of buying expensive decorations, get creative and make your own using non-toxic materials. You can also use plants from your garden or purchase affordable live plants online. But make sure you clean them properly before adding them to the tank and that you’re using cleaners and products safe for fish. 

Proper maintenance and care to prevent health issues

The best way to reduce unexpected costs is by properly maintaining your fish's environment. Regular water and filter changes, proper feeding, and monitoring water quality can help prevent common health issues.
