Who This Is For

These products are selected for those that love keeping fish as pets even if you are a starter of this hobby.

How big should a fish tank be?
The size of a fish tank depends on the numbers and types of fish that will live in it. The thing about the appropriate size of a fish tank is there is no right size. We will recommend a big tank because big fish tanks are easier to maintain than smaller ones. A larger tank gives more room for a fish to play and be happy.

Can freshwater fish and saltwater fish be in the same tank?
No, don’t try it. A freshwater fish and a saltwater fish can’t stay in the same tank because of their different survival mechanisms. Saltwater fish need salt to survive and freshwater fish can’t survive in a saline solution.

How to acclimate fish into a new fish tank?
After properly setting up your fish tank, turn off the lights in the tank and the room as these lights may affect the fish. Fish are usually sold in a bag and if it doesn’t come in a bag, put them in a small plastic bag filled with water. Now, float the bag in the fish tank for 15-30 minutes. After this specified duration has been achieved, cut open the bag from the top and fold the top edges of the bag to create an air pocket. Now that you have created an air channel, you need to get a measuring cup and slowly add a half cup of the fish tank water to the bag at intervals of four minutes until the bag is full. Once the bag is full, lift it out of the fish tank and pour half of the water away carefully. Place the bag back into the tank and fill it with a half cup of water every 4 minutes. Once the bag is full, dip a small net into the bag carefully and get the fish out. Then, introduce the fish into the tank quickly and gently.

Care and maintenance

Know the needs of your type of fish
Before you transfer your fish into a fish tank, know more about the fish. Discover what type of fish it is: “Is it a freshwater fish or saltwater fish?”, “What does it feed on?”, and “What temperature will suit it best?” If you don’t have a comprehensive understanding of your fish, you may end up killing it.

How to clean a fish tank
You can clean a fish tank while your fish is in the tank. Disconnect the tank from any power source to avoid electrical shock. Remove the filter and UV lights, and close all valves. Clean the glass or plastic with an appropriate scrub and remove all synthetic decor and scrub with a toothbrush and hot water. It is best to use a gravel vacuum to tidy the substrate crevices. Remember not to remove more than 50% of the tank water as you may lose some beneficial bacteria if you exceed that limit. Refill the tank with new chlorine-free water that has been treated with a conditioning treatment.

How often to clean a fish tank
This depends on the size of the fish tank, its filter system, the type of fish, and the number of fish. It is recommended that you check the fish tank every day for any environmental change. We will suggest that you change the water every week. You should monitor the pH, ammonia, and nitrate levels every month. If you do these steps diligently, you can do deep cleaning every two months.

Where to keep a fish tank
The best place to keep a fish tank is on a flat surface that is devoid of noise, direct sunlight, and traffic. It is good to place a fish tank where you can easily access it and others can see it. Make sure your fish tank is near an electrical socket and far from an air conditioner or any gadget that will change the temperature of the tank.

Using water treatments
There are many water treatments that you can deploy to make the tank water habitable. You can use ammonia removers, water clarifiers, pH modification, tap water conditioners, biological aids, phosphate removers, algae treatments, and aquarium salts.

Lights, heaters, and other potential features to keep handy
Your fish tank needs some essential gadgets to work efficiently. Such gadgets include lights, heaters, air pump regulators, filters, and fishnets. Some of these gadgets are powered by electricity so your tank needs to be close to an electrical socket.
