Dallas North Aquarium has served North Texas aquarium keepers for over 3 decades.
Located in Carrollton, the store carries freshwater fish, saltwater livestock, corals, plants, aquariums, equipment, food, and water-care products.
Some customers arrive with a detailed stocking plan. Others walk in holding a jar of cloudy tank water and hoping for answers. Both are welcome.
Freshwater Fish, Saltwater Fish, Corals, and More
Livestock is one of the main reasons to visit, and the selection changes throughout the week.
Freshwater shoppers may find tetras, barbs, rasboras, bettas, gouramis, rainbowfish, plecos, loaches, catfish, shrimp, snails, and African or American cichlids. Live plants are also available for customers building planted tanks.
The saltwater department carries a changing assortment of marine fish, corals, anemones, and invertebrates. Depending on the shipment, that may include clownfish, gobies, wrasses, tangs, puffers, shrimp, crabs, snails, and other reef animals.
Popular livestock can sell quickly. Customers searching for a particular fish or coral should check the latest arrivals and call the store to confirm that it is still available.
Finding Fish That Belong in the Tank
Choosing fish by appearance alone is an easy way to create problems. That small, peaceful-looking fish may grow much larger, become territorial, eat its tankmates, or require water conditions the aquarium cannot provide.
Before recommending livestock, the staff considers the tank’s size, current inhabitants, filtration, water conditions, and the customer’s experience level. This helps avoid common problems such as overcrowding, aggression, and incompatible tankmates.
Customers are encouraged to ask questions before buying. It is much easier to choose the right fish at the store than to catch the wrong one after it has claimed half the aquarium as private property.
Aquariums, Equipment, and Everyday Supplies
Dallas North Aquarium carries supplies for new builds, established tanks, and emergency repairs. The store’s selection includes aquariums, stands, filters, heaters, lighting, pumps, plumbing parts, test kits, water conditioners, food, medications, substrate, rock, driftwood, and maintenance tools.
Reef keepers can also find salt mixes, supplements, filtration products, lighting, and other marine aquarium equipment.
Customers who are unsure what they need can bring their tank size and setup information.
Staff members can help select equipment that works with the aquarium instead of simply pointing toward the biggest box on the shelf.
Setting Up a New Aquarium
A new aquarium needs time to become ready for fish. Filling a tank in the morning and stocking it that afternoon can lead to ammonia problems, sick livestock, and a rough introduction to the hobby.
The process begins with choosing an appropriate tank, filter, heater, lighting, and substrate for the livestock that you are wanting to house.
Once the aquarium is assembled and filled with conditioned water, it must establish the beneficial bacteria responsible for processing fish waste. This is known as cycling the tank.
Water should be tested before livestock is introduced. Fish should then be added in stages so the biological filter has time to adjust.
Customers planning a new setup can bring measurements, photographs of the intended space, and ideas about the fish they would like to keep. Those details make it easier to build a practical setup from the beginning.

Bring a Water Sample
Cloudy water, algae, sick fish, unusual behavior, and sudden livestock losses can have several possible causes. Guessing usually wastes time and may make matters worse.
Dallas North Aquarium offers free in-store water testing. Customers should bring a fresh water sample along with:
The aquarium’s size
A list of its inhabitants
Information about the filter and other equipment
Photos or video of the problem
Details about recent additions, treatments, or water changes
A water sample cannot explain everything, but it provides far more useful information than “something seems off.”
Professional Aquarium Services
For customers who need additional help, Dallas North Aquarium offers aquarium installation and maintenance for homes and businesses.
Service may include water changes, algae removal, water testing, equipment inspections, and other routine care based on the aquarium’s needs. Professional maintenance is available for freshwater, saltwater, reef, custom, and commercial displays.
This option works well for busy aquarium owners, businesses with display tanks, and anyone who would prefer to enjoy the aquarium without spending the weekend hauling buckets.
