Unique. Rewarding. Flexible. Profitable. Yours.

The neat little business no one thinks about. :)


My name is Larry and I own a business called Aquatic Designs, Inc.

That's me working in a 375 gallon aquarium in a hospital waiting room.

People ask me all of the time what I do for a living.

When I tell them, they sort of tilt their head, think for a second, then say,


They never ask their second question, but I know what it is.

"How in the world can you make a living cleaning aquariums?"

So, I just answer them back in my head...

"Well, I make a very good living....thank you."

In Fact:

I have been managing aquariums as a business for

-25 years-

and have been doing it full time for the last

-15 years-

All at an average of $75+ per hour.**

Now, you just tilted your head and said,


Didn't you?


Have you been thinking of starting your own side business?

Are you having a hard time coming up with good ideas, though?

  • Something different that not everyone else is doing?
  • Something that doesn't cost a lot of money to get started?
  • Something that doesn't require a large overhead?
  • Something with flexible hours?

This is my business.

The general idea of this business is that you service fish aquariums that either a client already owns or that you sell and setup for them.

They will pay you each month to:

  • Clean the tank
  • Check water quality
  • Inspect the fish
  • Service the equipment

All pretty basic.

Your first thought may be:

"I have no idea how to take care of a fish aquarium!"

Neither do most other people.

I like to call that job security.

So, that's why they hire me to take care of their aquarium.

If you don't know anything about aquariums, that's OK.

My course here at Teachable will teach you what you need to know to be able to install and maintain aquariums in a maintenance environment.

And get paid for it.

Hospital Waiting Room - Customer Since 2002

Your second thought may be:

"Isn't cleaning an aquarium a lot of work and messy?"

If it was, I wouldn't be doing it.

I have several aquariums in sensitive areas at Arkansas Children's Hospital.

If I created a mess while cleaning them, they wouldn't keep them there for long.

With the right equipment and the right knowledge, cleaning an aquarium can easily be done in just a few minutes.

"Hey, I just wanted to let you know I finished the course today. It was very informative for someone who doesn’t have a lot of experience with larger aquariums or what equipment to use on certain types of tanks.

I think the most important things I read in there (in my opinion) were the legal aspects behind operating this kind of business.

All in all it was very informative and it gave really good advice."

In 1995, my wife and I scraped up $2500 and bought an aquarium maintenance business from a friend who had to move out of town.

Since then, I have installed and maintained fish aquariums in all types of places. I have maintained everything from betta bowls to 4000 gallon monsters that I've had to dive into. I've estimated that I have walked up to aquariums to perform maintenance on them at least 10,000 times.

I still manage over 60 aquariums in my business today.

So, who would this business be perfect for?

Those who are:

  • Wanting to open their own side business to add extra income or pay off debt.
  • Feeling like they're stuck in their current job with no way out.
  • Wanting to start their own business but don't have a lot of money to spend.
  • Students wanting a part time job but desiring to make more money for less hours.
  • Stay-at-home parents who want a little side hustle now that the kids are in school.
  • Teens with the entrepreneurial bug.

Who is it not for?

Those who:

  • Are living in a rural area without much opportunity to gain new business.
  • Have current schedules that would not allow them to access accounts during their available hours.
  • Are not able to work with other people.
  • Are not willing to put in the work to start a new business.

Requirements are:

  • Able to do physical labor such as lifting aquariums for setup or have access to people who can.
  • Able to transport aquariums for setup or have access to people who can.
  • Able to transport basic cleaning equipment in between accounts.
  • Able to interact professionally with customers and give awesome customer service.
  • Patient and willing to put in the work to get new accounts.
  • Able to pay attention to details.
  • Able to visit accounts during their available hours.

This is not a get rich quick business.

You are selling a luxury service so it can take some effort to acquire new accounts. Once you get those accounts, though, they tend to be loyal and provide a consistent, predictable, monthly income.

I have had many of my accounts for 15+ years and even one that has been with me for almost 25 years. That one account has netted me almost $50,000 over time.

The pros of this business are:

  • There's normally not a large amount of competition.
  • In my business model, you are paid on a monthly (or project) basis, not an hourly basis.
  • It is not seasonal. Aquariums need servicing the same whether it's July 4th or Christmas.
  • It's a consistent, predictable, monthly income stream.
  • The work hours can be flexible.
  • The work is indoors out of the weather.
  • You don't have to have a storefront or pay rent.
  • You don't have to have employees.

The cons are:

  • Sometimes aquariums misbehave and they have to have extra attention, reducing your "dollar per hour".
  • Fish can sometimes get sick and die.
  • Sometimes problems arise and you will have to research to find a solution.

This business is basic enough that it has the potential to be profitable within the first year.

"Wow just Wow! Everything I know from my years of being in this hobby and I still learned a bunch from this program. This course breaks down everything from what tools to have to how to get clients to even covering the legal aspects of this business. Even with my own home aquariums I learned some extra tips. One of the best things is that this course has links for buying supplies and equipment at wholesale. I'm confident that after this course and some hard work I can have and run a successful aquarium maintenance business."
