Introducing our FW Nano Fish Tanks

If you are an aquarist on a budget, or you are restricted by a small living space, the nano tank is the perfect solution for you. Set-up is simple and this new model makes maintenance easier than ever! Each tank has a filter tray that is supplied with fine filter foam that can be simply accessed just by lifting the top of the hood - So now there is no need to take the whole thing off! The FW tanks also come with a 250 litres per hour pump with venturi as well as built-in eco-friendly LED lighting.

FW Nano Tank


Owning a nano tank can be a fun family, or solo, an activity that can have a lot of educational, and even therapeutic value. We would like to advise that some research is done prior to setting up the tank. Take some time to sit down and learn more about cycling tanks, water clarity, and water stability (i.e. how to keep water temperatures steady!). 

Once you are well informed about your tank, it is time to get it set-up:

Make sure your tank is free of any damage when it comes out of the packaging. If it is clear of damage, then clean the aquarium thoroughly (inside and out) using FRESH WATER ONLY. Do not use any soap! And if you are using a sponge or towel to clean it, make sure those items have not come in contact with soap. Next, find a good place for your aquarium that is away from electrical equipment, direct sunlight and heat sources.

The filters will need to be removed from their packaging and washed with FRESH WATER ONLY before being placed in filter bay, which is in the hood of the tank. Remember to put the coarse foam on the bottom and the fine filter foam on top.

Last, attach your aquarium pump to the underside of your filter tray using the attachment that has been provided.

Clean your tank ornaments and gravel with fresh water. Again, NO SOAP! Add the clean gravel and then fill the tank half way with water. After putting some water in the tank, place the decorations where you would like them and then add an aquarium water conditioner and filter start treatment. After this is done, add the rest of the water! Fill it until the water reaches just under the rim of the nano aquarium. This is also the best time to put in live plants.

A couple things to remember:

  • If you wish to keep tropical fish, you will need a heater for the water.

  • Before you can add any fish to your new nano tank you must fully cycle your tank. Be patient though, this can take up to 4 weeks to complete. Your water can be tested at home using a testing kit and thermometer, or at a local aquatics store.

While your fish tank is being cycled, think about what fish you wish to keep and if they are appropriate for the size of your aquarium. The FW-7 holds 7 litres of water and is 230 x 160 x 275 mm (LxWxH). The best inhabitants for this tank would be live plants, Siamese Fighting Fish, and shrimp! 

The FW-14 holds 14 litres of water and is 290 x 200 x 330 mm. This tank would be suitable for a Siamese Fighting Fish. Make sure that the males are housed alone due to their aggressive nature. They call them fighter fish for a reason! You could also get Clown Killifish or Lampeyes.

The FW-29, which holds 29 litres of water and is 380 x 260 x 405 mm, gives you quite a few more options for fish to keep. Tetras can be perfect because they do not grow to be very big and they are easy to look after! They are schooling fish, which means they should be kept with about 6 others of their kind. Try the neon tetra, lemon tetra, or the cardinal tetra. Other than tetras, rasboras, guppies, and minnows would be ideal for a nano tank of this size.

Avoid adding too many fish to your aquarium because you will find water quality becomes very difficult to keep up with. We recommend a minimum of 3 litres of water for every 1cm of fish, including the tail.

Adding Fish

Float the fish in their bag inside the aquarium – add a little water from the aquarium to the bag and acclimatise for 15 minutes; this will regulate the water temperature in the bag and reduce the risk of making your inhabitants stressed. Carefully remove the fish from their bag using a net, and place them in the aquarium. When all of the inhabitants are settled in, top up the tank with water.

Due to the small size of nano tanks, water cycles occur more quickly. Please remember to regularly check the water quality and temperatures and keep a close eye on your fish. After a while you will get the hang of your aquarium’s maintenance schedule.
