Part 1 - How to start an Aquarium Maintenance business - Background
Many people enjoy having fish, as they’re a relaxing and peaceful pet. People don’t always, however, have the time or inclination to properly look after a fish tank. An aquarium maintenance business cleans and maintains aquariums, usually serving both businesses and individuals. These businesses let people have beautiful, healthy aquariums without personally cleaning them.
Our guide is in 3 parts:
- Part 1 - How to start an Aquarium business - Background
- Part 2 - Our planner tool to see if this idea is the right fit for you
- Part 3 - Action plan to get started
What are the costs involved in opening an aquarium maintenance business?
The startup costs for an aquarium maintenance business are minimal.
The largest expenses are a vehicle for getting to clients’ sites and an office/storage space, but many business owners keep these costs low by using a room in their home and their personal vehicle. A business owner can invest in an outfitted vehicle and office space after their business is established, but in the beginning these things likely won’t be necessary.
Other startup expenses include insurance premiums, advertising fees, and equipment and supplies. Advanced Aquarium Concepts has an in-depth list of supplies that business owners may want. The list includes, among other things:
-
5-gallon buckets
-
towels (of various sizes)
-
algae pads (with and without handles)
-
razors and an X-acto knife
-
specimen containers
-
water changers
-
other supplies
What are the ongoing expenses for an aquarium maintenance business?
The ongoing expenses for an aquarium business are relatively low. They include vehicle maintenance costs, fuel, insurance premiums, advertising fees and supply costs. Supply costs are minimal in the industry, as just a small amount of a supply can usually treat a lot of water.
Who is the target market?
An aquarium maintenance business’ ideal client is a pet store that sells fish. Pet stores not only have multiple aquariums that need to be cleaned, but they’re also where people go to purchase fish and fish tanks. These stores can be a source of both ongoing work and other potential clients.
How does an aquarium maintenance business make money?
An aquarium business makes money by charging clients for aquarium maintenance and cleaning services. While fees are usually based on the service provided, they may be calculated from a desired hourly rate. For instance, a business owner that wants to earn $60 per hour might charge $45 for a service that they expect will take 45 minutes to do.
How much can you charge customers?
Many aquarium maintenance businesses charge about $1 per gallon for service calls. Some businesses, however, charge significantly less, but choose to only service larger aquariums. For example, Clear Aquarium charges as little as $0.55 per gallon, but they won’t service aquariums under 100 gallons.
In addition to regular service charges, most businesses also charge for emergency calls. These calls are usually priced by the hour. Clear Aquarium assess a $50 per hour fee for emergency calls during business hours and $75 per hour during off hours.
How much profit can an aquarium maintenance business make?
With a full list of clients, an aquarium maintenance business can make a significant revenue. A business owner who charged $50 per hour would earn around $1,000 – $1,500 per week working full-time hours, not counting travel and transition time. Even after expenses are subtracted, this is still a respectable income.
How can you make your business more profitable?
An aquarium maintenance business can increase its revenue by also offering tank installations, and selling fish and other supplies.
Day-to-Day and Growth
What happens during a typical day at an aquarium maintenance business?
An aquarium maintenance business owner spends much of their day driving to clients’ sites and cleaning their aquariums. Cleaning an aquarium can involve:
-
testing water for proper chemical balances
-
checking and changing filters
-
wiping algae off of the aquarium glass
-
assessing the health of fish
-
addressing any other issues that arise
-
other tasks related to keeping the aquarium clean and healthy
At the end of a service, business owners typically review what was done with the aquarium owner and make any recommendations that are appropriate.
When not actively servicing aquariums, business owners spend time cleaning their equipment, maintaining their own stock of fish and plants, ordering supplies, billing clients and seeking new clients.
What are some skills and experiences that will help you build a successful aquarium maintenance business?
An aquarium business owner should be extremely familiar with freshwater and saltwater aquariums, and the fish, plants, and other creatures that inhabit them. If business owners don’t have in-depth knowledge, clients may assume they’re paying a lot of money for someone who has a few buckets and brushes.
Business owners who don’t already possess this knowledge have a variety of resources available to them. The Ornamental Aquatic Trade Association offers a certificate and an advanced diploma, and ACS Distance Education has a 100-hour Aquarium Management program. Just a few of the many books written on aquarium maintenance include Freshwater Aquariums for Dummies, Saltwater Aquariums for Dummies, the Aquariums series (which covers freshwater, saltwater and reef aquariums), Aquarium Plants and Aquarium Corals.
In addition to taking a course and reading about aquariums, it’s also a good idea for new business owners to get some hands-on experience. Working for another aquarium maintenance business gives business owners a chance to learn about aquariums and the industry.
What is the growth potential for an aquarium maintenance business?
Most aquarium maintenance businesses service a single region. They’re generally located in cities, where there are more businesses and people who may want aquariums. Fish Geeks and Aquarium Design and Maintenance are two examples of businesses that service a single area.
What are some insider tips for jump starting an aquarium maintenance business?
While business owners may care for fish and other aquatic creatures, it’s people that pay for their service. How business owners interact with their clients is extremely important.
When seeing a new client’s aquarium for the first time, business owners should find something to compliment. Business owners can complement clients on the cleanliness of their aquarium, the health of their fish, a well-conceived set-up, or any other thing they think of. Complimenting clients puts them at ease and helps them feel accomplished, and it will also help them receive whatever constructive feedback you may want to offer them in terms of how they are caring for their aquatic pets.
How and when to build a team
Most aquarium maintenance businesses can be run as a one-person operation. If a business gets more clients than a single person is able to service, an employee may need to be hired. Additionally, very large tanks may sometimes require two people to clean, but it is unlikely that newer businesses will service tanks like this.

Part 3 - Action plan to launch your Aquarium Maintenance business in 90 days
Nine concrete steps to take you from idea to open business, grouped into 30-day phases. Complete the planner above and we'll highlight what's most important for your situation.
First 30 days — Foundation
-
Form your legal entity
An LLC keeps your personal assets separate from business debts and lawsuits — the most common reason small business owners choose this structure. Sole proprietorships and partnerships do not provide this protection.
-
Get an EIN and register for taxes
Apply for your free Employer Identification Number through the IRS, then register for any state or local taxes that apply to your business (sales tax, franchise tax).
-
Open a business bank account and credit card
A dedicated business account is required to maintain personal asset protection. Mixing personal and business finances ('piercing the corporate veil') can void your LLC's liability shield.
-
Set up business accounting
Recording expenses and income from day one makes tax filing easier and lets you see when the business is actually profitable. Use software (QuickBooks, Wave) or a part-time bookkeeper.
Days 30–60 — Compliance & Risk
-
Get permits and licenses
State and local requirements vary widely. Brick-and-mortar businesses typically need a Certificate of Occupancy; service businesses may need specific professional licensing; food businesses need health permits.
-
Get business insurance
General Liability Insurance is the most common starting point. If you'll have employees, most states require Workers' Compensation. Specific industries need additional coverage (product liability, professional liability, etc.).
Days 60–90 — Launch
-
Define your brand
Your brand is how customers perceive and remember you. A clear name, logo, and visual identity make every later marketing decision easier and protect you legally as you grow.
-
Create your business website
Every legitimate business needs a website. Social media pages are not a substitute — you don't own the platform. Modern website builders mean you can launch a clean site in a weekend without a developer.
-
Set up your business phone system
A dedicated business number keeps your personal life private, makes the business look legitimate, and lets you route calls professionally. Cloud phone services start under $20/month.
