You can simply search online for your city, region, or state, along with the words “aquarium” and “distributor” to find a supplier in your area. Although buying your stock from a distributor is a tad more expensive than buying it directly from the manufacturer, a distributor will fill smaller orders (like for a small business) where manufacturers often will not.  Distributors are also sometimes called wholesalers, brokers, or jobbers. You can also ask your competitors who they get their supplies from, although they probably won’t be too keen to help you. You’ll need to secure supplies of tanks and tank lids, stands, filtration and aeration systems, water treatment systems, tank scrubbers, decor, and anything else that a potential customer might need for their aquarium. Place a small order with your wholesaler at first to get a sense of how much product you can move in a set amount of time. You won’t be able to turn as much of a profit by sticking to 1 or 2 types of fish, like guppies or goldfish. By selling more exotic species as well, you will not only appeal to a broader clientele, but will also be able to sell more valuable (and profitable) items.  You can acquire your fish either from saltwater fish collectors, who capture the fish in the wild, or from freshwater fish farms. Note that you’ll need to know how to take care of exotic fish before you can buy them and sell them in your store. Examples of exotic fish to stock in your store may include African cichlids, angelfish, or swordtails. You should also aim to stock both freshwater and saltwater fish. Although most home aquariums house freshwater fish, you’ll want to make sure you’re catering to as many potential customers as possible. while they’re in your possession. The fish aren’t just your means of making an income; they’re also living creatures that need to be taken care of. Be sure you’re adequately feeding and housing the fish you’re selling and monitor their health for any signs of illness.  Make sure you feed the fish the right type of food each day. For example, some species of fish eat tropical flakes, while others eat bloodworms, while still others eat shrimp eggs and krill. Measure the pH levels in the tank each week to make sure they’re within an acceptable range for the type of fish in the aquarium. Clean each aquarium each week and replace the filter every month.
