This aquarium is about as basic as they come.
It’s an average 50 gallon freshwater aquarium with average tropical fish.
The reason it’s on here is because it is the oldest aquarium that I have.
This aquarium was installed in another business over 25 years ago and was moved to this business over 20 years ago. It is a rental aquarium so my initial investment of around $700 has brought in over $18,000 in its lifetime. I probably spend 8 hrs a year on this tank which will make me around $90 per hr.
It’s the basic, unassuming aquariums that can actually be the most profitable for my business.
