How Much Are Goldfish – Uncovering The Full Cost For A Thriving Tank
Let’s be honest. When you think of a pet goldfish, you probably picture a tiny fish swimming in a small glass bowl, a prize won at a local fair for less than a dollar. It’s a common image, and it leads many to believe that goldfish are one of the cheapest and easiest pets you can own.
Here at Aquifarm, we want to let you in on a little secret known by experienced aquarists: the sticker price of the fish is just the tip of the iceberg.

Don’t worry—we promise to guide you through every step of budgeting for your new aquatic friend, helping you avoid common mistakes and setting you up for years of enjoyment.
In this complete guide, we’ll break down the initial price of different goldfish varieties, explore the essential setup costs that form the foundation of a healthy tank, detail the ongoing expenses you can expect, and even provide sample budgets. By the end, you’ll have a crystal-clear understanding of the true investment, empowering you to build a stunning aquarium where your goldfish can truly thrive.
The Sticker Price: A Breakdown of Goldfish Types and Costs
The first stop on our journey is the fish store itself. You’ll quickly notice that not all goldfish are created equal, and their prices can range from a few cents to hundreds of dollars. Understanding the difference is the first step in our how much are goldfish guide.
Common & Feeder Goldfish (Comets, Shubunkins)
These are the classic, streamlined goldfish you’re most familiar with. Comets are typically solid orange, while Shubunkins have a beautiful calico pattern. They are incredibly hardy and active swimmers.
- Average Cost: $0.25 – $5.00
- Aquifarm Pro Tip: While cheap, these fish are bred for quantity, not always quality. More importantly, they grow massive—often over a foot long! They require ponds or very large aquariums (75+ gallons) to live a full life, making their low initial price deceptive.
Beginner-Friendly Fancy Goldfish (Fantails, Ryukins, Black Moors)
These are the charming, egg-shaped goldfish with double tails that capture everyone’s hearts. They are slower swimmers, making them better suited for aquarium life than their common cousins. Don’t worry—these fish are perfect for beginners!
- Average Cost: $5.00 – $25.00
- Why We Love Them: Fantails, Ryukins, and Black Moors are generally robust and forgiving as you learn. They have all the personality of fancy goldfish without the highly specialized care some other varieties demand. This is a great place to start your how much are goldfish care guide journey.
Intermediate & Collector-Grade Fancy Goldfish (Orandas, Ranchus, Lionheads)
Now we’re getting into the showstoppers. Orandas have a magnificent “wen” or crown-like growth on their head, while Ranchus and Lionheads are known as “buffalo-heads” for their lack of a dorsal fin and prominent head growth.
- Average Cost: $25.00 – $150.00+
- Heads Up: Their unique features require pristine water conditions and specialized care. Their wens can overgrow and impede vision, and their swimming ability is more compromised. These are stunning fish, but best left to aquarists with some experience under their belt.
Where to Buy: Pet Store vs. Specialist Breeder
You can find common and some fancy goldfish at large chain pet stores. For healthier, higher-quality, or more exotic varieties, a local fish store or a specialized online breeder is your best bet. Breeders often provide fish with better genetics and a healthier start in life, which can save you money on vet care down the road.
Beyond the Fish: Budgeting for Your Goldfish’s First Home
Here’s where we get to the heart of the matter. A goldfish’s health is directly tied to its environment. Investing in the right setup from day one is the most important financial decision you’ll make. This is where how much are goldfish best practices truly come into play.
The Aquarium Itself: Size Matters Most!
Please, hear us on this: goldfish do not belong in bowls. Bowls are unfiltered, unheated, and far too small, leading to ammonia poisoning, stunted growth, and a drastically shortened lifespan. It’s one of the most common problems with how much are goldfish budgeting—underestimating the tank size.
A happy goldfish needs space. Our rule of thumb:
- For Fancy Goldfish: Start with a 20-gallon tank for one. Add 10-15 gallons for each additional fancy goldfish. A 40-gallon “breeder” style tank is a fantastic, spacious home for two or three.
- Estimated Cost: $30 (for a 20-gallon) to $150+ (for a 40-gallon or larger, often found cheaper during sales).
Filtration: The Unsung Hero of Your Tank
Goldfish are charming but notoriously messy. They produce a lot of waste, which creates toxic ammonia in the water. A powerful filter is non-negotiable.
- Hang-on-Back (HOB) Filters: Great for beginner tanks (20-40 gallons). They are easy to use and maintain. Cost: $30 – $60.
- Canister Filters: The gold standard for larger tanks (40+ gallons). They offer superior filtration capacity and are quieter, but have a higher upfront cost. Cost: $80 – $200+.
Pro Tip: Always buy a filter rated for a tank larger than the one you have. For a 40-gallon tank, get a filter rated for 50-75 gallons. You can’t over-filter a goldfish tank!
Substrate, Decor, and Lighting
This is the fun part where you get to be creative!
- Substrate: Fine, smooth gravel or sand is best. Goldfish love to sift through the substrate, and sharp gravel can injure their mouths. Cost: $20 – $40.
- Decor: Choose smooth rocks, driftwood, and silk or live plants. Avoid anything with sharp edges that could tear delicate fins. Cost: $20 – $60+.
- Lighting: A simple LED light will make your fish’s colors pop and help live plants grow. Cost: $30 – $70.
Essential Accessories: The Little Things That Add Up
Don’t forget these crucial items! This list is key to understanding how to how much are goldfish budgeting works in practice.
- Water Test Kit: An API Freshwater Master Test Kit is essential for monitoring ammonia, nitrite, and nitrate. This is your window into the health of your aquarium. Do not skip this! Cost: ~$35.
- Water Conditioner: Tap water contains chlorine that is lethal to fish. A bottle of Seachem Prime or a similar dechlorinator is a must-have for every water change. Cost: ~$10.
- Gravel Vacuum/Siphon: The tool you’ll use for weekly water changes and cleaning. Cost: ~$15.
- Buckets: At least two 5-gallon buckets dedicated only to aquarium use. Cost: ~$10.
- Fish Net & Thermometer: Basic but necessary. Cost: ~$10.
The Ongoing Commitment: Recurring Goldfish Care Costs
Once your tank is set up, the costs become much more manageable. Thinking about these recurring expenses is one of the most important how much are goldfish tips we can offer for long-term success.
Food: Fueling Your Finny Friend
A high-quality, sinking pellet or gel food should be the staple of your goldfish’s diet. This prevents them from gulping air at the surface, which can cause buoyancy issues. You can supplement their diet with blanched vegetables like peas and spinach.
- Estimated Monthly Cost: $5 – $15.
Water Care & Maintenance
You’ll need to replenish your supplies over time. This is where the long-term benefits of how much are goldfish planning become clear—no surprise expenses!
- Water Conditioner: A bottle lasts a surprisingly long time. Cost: ~$20-30 per year.
- Filter Media: Depending on your filter type, you may need to replace cartridges or rinse sponges. Cost: ~$20-50 per year.
- Electricity: The cost to run a filter and light 24/7 is minimal, but it’s a factor. Cost: ~$5-10 per month.
Health & Wellness: The “Just in Case” Fund
Even with the best care, fish can get sick. It’s wise to have a small “medicine cabinet” on hand for common ailments. This includes aquarium salt, Ich-X, and a general antibiotic. Having a small 10-gallon tank for quarantine is also a fantastic idea.
- Estimated “Just in Case” Fund: $50.
A Sustainable and Eco-Friendly Approach to Goldfish Keeping
Being a responsible aquarist goes beyond just your tank. Adopting a sustainable how much are goldfish mindset benefits both your wallet and the environment.

Reducing Waste and Water Usage
Don’t just pour old tank water down the drain! It’s full of nitrates, which are fantastic fertilizer for houseplants and gardens. Invest in durable equipment like a quality canister filter that will last for years, rather than cheap HOBs with disposable cartridges that create plastic waste.
The Problem with “Releasing” Goldfish
It is never okay to release a pet goldfish into a local pond or river. They are an invasive species that can decimate local ecosystems. If you can no longer care for your fish, please rehome it through a local aquarium club or fish store.
