Estimates for a small start in the UK, not guarantees.

What it is

An online shop selling dry goods for fishkeeping, such as food, filters, lighting, décor, water treatments and sometimes hardy aquatic plants. Live fish are left out at the start because of the care and welfare rules.

Your first three steps

  1. Choose a niche, for example planted tanks, shrimp or coldwater, and check what UK competitors already offer
  2. Open accounts with a few aquatic wholesalers and order a small test range
  3. Set up a simple online shop or marketplace listings and sell your first orders to friends and local fishkeeping groups
Who pays

Hobbyists who want a wider range or better prices than they can find locally, including those buying for planted or specialist tanks.

How it makes money

Margin on products sold through your own website or marketplaces, with repeat orders for food and treatments. You can focus on a niche such as planted tanks or shrimp keeping.
