About the Business
Total Aquaculture is a well-established Perth-based business specialising in the supply and maintenance of fresh and saltwater fishtanks for restaurants and seafood venues. The business services clients across Perth metro and surrounding areas, providing a niche and highly valued service that allows venues to showcase live seafood and maintain high-quality display aquariums.
The business currently services 15 active clients, with the majority on ongoing monthly service contracts. 11 of these clients have been with the business for over 6 years, demonstrating strong long-term relationships, trust, and reliable recurring income. This provides a stable and predictable foundation with minimal client turnover.
The business generates approximately $7,000 per month in profit (~$84,000 per year) with low operating expenses of around $1,250 per month. This results in high net margins and a simple cost structure. The operation is run by a single owner/operator working approximately 20 hours per week, making it a flexible and lifestyle-friendly business.
No formal qualifications or licences are required to operate the business. Full training and handover will be provided, making it suitable for a first-time business owner or someone looking for a low-stress, semi-passive income stream.

The business phone number will also be transferred to the new owner.
There is currently minimal marketing in place, creating strong opportunity for growth. Expansion potential exists through increased outreach to hospitality venues, scaling service routes, and introducing digital systems such as a CRM and online presence.
