Don’t Let Your Dream Tank Become a Nightmare: The Critical Questions Every Fish Store Customer Must Ask Before Buying
Walking into a fish store can be an exhilarating experience. The vibrant colors, graceful movements, and endless variety of aquatic life can make even the most seasoned hobbyist feel like a kid in a candy store. However, beneath the surface of this aquatic wonderland lies a crucial truth: making any livestock purchase requires asking important questions to make sure you’re making the right decisions for yourself and the fish.
The difference between a thriving aquarium and a costly disaster often comes down to the questions you ask—or don’t ask—before making a purchase. Whether you’re a beginner setting up your first tank or an experienced aquarist expanding your collection, understanding what to inquire about can save you money, heartache, and most importantly, the lives of your aquatic companions.
Size Matters: Understanding Adult Fish Dimensions
One of the most critical questions to ask is about the fish’s adult size. Many of the pet fish species you see in the store aren’t fully grown, and some may double, triple or more in size. That adorable 2-inch fish might grow into a foot-long giant that outgrows your tank within months. Always make sure the fish you intend to buy will fit comfortably in your aquarium when they reach adult size.
Compatibility: The Foundation of a Peaceful Community
Fish compatibility extends far beyond simply putting colorful species together. Incompatible fish can lead to increased stress for all tank mates, which can result in illness, injury and an overall decline in health. Before purchasing, keep a list of the fish you have in your aquarium, and if you’ve forgotten or aren’t sure what kinds of fish you have, take pictures to show store staff so they can help you make the right choices.
Many fish spend their time at specific levels in the water column, and it’s important both visually and in terms of compatibility to have equal proportions of surface, mid-water and bottom dwellers, as crowding fish in any layer may result in conflict and stress.
Water Parameters: The Invisible Foundation of Fish Health
Water chemistry might seem technical, but it’s fundamental to fish survival. While most tropical fish sold today are raised in captivity and tolerate a certain range of water chemistry parameters, some are still collected in the wild and may need a specific pH, alkalinity or temperature to thrive, so always research the type of fish you intend to buy or ask if they need special conditions.
The best parameters for your fish tank depend on species being kept, as every species has their own specific set of needs that should be considered when determining the best parameters for your tank. Don’t assume all tropical fish have identical requirements.
Feeding Requirements: Beyond Basic Flakes
Understanding dietary needs is crucial for long-term fish health. While most tropical fish do just fine on a diet of flake, pellet or frozen foods, some species are specialized feeders that may require live food or customized feeding methods. Ask about specific feeding requirements, frequency, and any special dietary considerations before committing to a purchase.
Timing Your Purchase: The Importance of Acclimation
Patience is a virtue in fishkeeping. Never buy a fish that has just arrived in the store, as shipping stress temporarily lowers a fish’s resistance and increases its susceptibility to disease, and moving it again without giving it a few days to stabilize will only compound the problem.

Red Flags to Watch For
A reputable fish store should encourage questions, not discourage them. Look around the shop, see how clean it is, check for any poorly fish, and ask the staff some simple questions—the answers will normally give you an idea of how well the fish are being looked after. Staff should be knowledgeable about compatibility, water parameters, and care requirements.
The Long-Term Perspective
Remember that fishkeeping is a long-term commitment. Owning an aquarium is a hobby like any other—it requires time, money, and dedication to get the most out of it. The questions you ask today will determine your success for years to come.
By asking the right questions before making a purchase, you’re not just buying fish—you’re investing in a thriving aquatic ecosystem. Take the time to understand compatibility, water requirements, feeding needs, and adult sizes. Your patience and diligence will be rewarded with a beautiful, healthy aquarium that brings joy for years to come.
