The Aqua One 320 can hold around 9 tropical and 4 cold water fish based on them being around 3cm as adults. Things to consider when purchasing this aquarium is there have been reports of the lamination not being of the best quality and the wooden effect peeling off. In addition to this, it is a tall cabinet with no shelves. So if you are looking for an aquarium that will double as a storage area, then this may not be the one for you. These attach to the bottom of your tank with a suction cup and due to invisible wires really do appear to be defying gravity. Finally add some vibrant colour in the form of bright orange, blue, purple, yellow, red and pink vibrant plants. Starting at 65 litre tank part of the Start collection meant for beginners in fish keeping. Also part of the Start family are the 320 (28L) and the 340 (40L), although these are more square than the 500’s pronounced rectangular shape. The Aqua One 500 can hold around 21 tropical and 10 cold water fish based on them being around 3cm as adults. For marine you should have 3 inch of fish for every square foot of tank.

This particular product allows for seamless viewing with curved glass corners. This aquarium can accommodate both freshwater and tropical fish. When shopping for a fish tank, you want to be sure that you think of everything, even the lighting. It does not come with a heater so if you are going for a tropical tank you will need to buy either the thermosafe or glass thermometer suitable for a 100 litre tank. A 100 litre tank will have the capacity for 33 tropical and 15 cold water fish. This is based on adult fish of 3cm.

This tank is fitted with the wet and dry filtration system which is located in the slim line hood reserving more space in the tank for fish. It also being an external filter has a higher intake of oxygen making it more efficient than internal filters. Internal filters are generally cheaper and run quieter as they are placed inside a body of water, however if your tank is small then you may find yourself trying to balance having a nice looking tank versus a bare minimum glass tank.

This tank is not suitable for marine fish. This tank comes with an internal filter but no heating unit. Aqua One do manufacture their own range to fit every tank they make though. You have a choice of two heaters, the Aqua One thermometer (glass) or the thermosafe which are both suitable for tanks up to 100 litre.

The lighting is (I believe) a 7.2W LED but no idea about temperature or spectrum. Is it worth / necessary to replace this with something a bit better or as the tank is so small will this be OK? This is a 28 litre tank part of the Start collection meant for beginners in fish keeping or those looking for something that does not require a large amount of maintenance. It is an award-winning aquarium (like most Aqua One Fish Tanks) that is stylish, functional, and very easy to keep up with. You can forgo the pump and heater and simply use this for cold water fish as it works well with them too. This tank comes complete with: built in sump, pipe work, filtration media, heart, protein skimmer, circulation pump and Quadrolite 4 tube T5 lighting system.
