The size of an aquarium should depend on several factors, including the type of fish or aquatic life you plan to keep, their size, and their specific requirements. Here are some general guidelines to help you determine the appropriate size for your aquarium: 

Research your fish: Different species of fish have varying space requirements. Some fish are small and can thrive in smaller aquariums, while others are large and need more room to swim comfortably. Research the specific needs of the fish you intend to keep. 

• Consider the fish's adult size: It's essential to consider the adult size of the fish, not just their current size. Many fish grow significantly as they mature, and you should plan for their long-term needs. 
• Water quality and stability: Larger aquariums tend to have more stable water conditions, making it easier to maintain proper water quality and temperature. Smaller aquariums can be more challenging to keep stable. 
• Filtration and maintenance: Larger aquariums (and larger fish) generally require more significant filtration systems and maintenance. Consider your willingness and ability to maintain the aquarium properly. Our Fish Tank Filters range offers various options to suit different tank sizes and types, ensuring optimal filtration.
• Aquascape and decoration: The size of your aquarium also affects the design and decoration possibilities. Larger aquariums offer more space for aqua scaping and creating natural environments for your fish. 
• Compatibility: If you plan to keep multiple fish species, consider their compatibility and space requirements. Some fish may be territorial and require more space to coexist peacefully. 
• Budget: Larger aquariums can be more expensive to set up and maintain. Consider your budget when deciding on the aquarium size. 

If you wish to discuss these items further our colleagues in store will be happy to help you. Our range of tropical fish tanks and cabinets offers various sizes and styles to suit different needs and spaces. All of our fish tanks are given a ‘Fish Points’ value, Fish points are an easy to use guide to help you determine which and how many fish are suitable for your tank. All fish are scored based on a number of factors such as size, how much waste they produce and whether they prefer to shoal in small or large groups. Did you know? Your aquarium needs to be big enough for the size your fish could grow to.

There are a few species which are ideal for beginners and new aquariums. Some of these are listed below: 

Mollies (available in a variety of breeds) – great for first-time fish keepers; a suitable species for a new aquarium

Harlequin Rasbora – a great community fish, ideal for new aquariums and beginners

Bronze Corys – hardy and easy to keep; suitable for first-time fish keepers

Black Widows – good beginner fish; best kept in small groups as they can be a little boisterous

Cherry Barbs

Golden Barbs

Swordtails

Tropical Platies

There are some other species that are good for beginners, but require an established aquarium, Guppies, Neon Tetra, black neon tetra and Cardinals. You should only add these if your aquarium has cycled and the fish living in there are compatible and healthy. 

Common tropical fish that are popular in the aquarium hobby include: 

• Guppies  
• Tetras 
• Angelfish  
• Betta Fish  
• Mollies  
• Rainbowfish  
• Gouramis  
• Plecos  
• African Cichlids 

Yes, it is important to allow a period of darkness within your aquarium at night. This allows your fish to rest. Rest is necessary to maintain good health.  

Tropical fish, like most fish, do not necessarily "like" or require direct sunlight. In fact, direct sunlight can often be harmful to aquarium fish. Here are some key considerations: 

Temperature Control: Direct sunlight can significantly raise the water temperature in an aquarium, which can be detrimental to tropical fish. Maintaining a stable and appropriate water temperature is crucial for their health. Fluctuations caused by sunlight can be stressful and potentially harmful. 

Algae Growth: Sunlight can promote the growth of algae in the aquarium. Excessive algae can consume oxygen, reduce water quality, and compete with live plants for resources. It may also look unsightly 

To provide appropriate lighting for a tropical fish aquarium, it's generally better to use artificial lighting systems specifically designed for aquariums. These lights can be controlled to mimic the natural light cycle and intensity that fish and plants in the aquarium need. Additionally, they won't have the negative side effects of direct sunlight. 

It's important to research the lighting requirements of the specific fish and plants in your aquarium, as different species may have different needs when it comes to the duration and intensity of light. 

Our Fish Tank Heater & Accessories collection offers a variety of options to suit different tank sizes and requirements.

Tropical fish usually require a water temperature that falls within the range of 24 to 28 degrees Celsius. This temperature range is suitable for many common tropical fish species. However, it's important to note that specific fish species may have slightly different temperature requirements, so it's a good idea to research the specific needs of the fish you plan to keep in your aquarium. 

Your fish may be a bit nervous and hide for a while, let them settle down for a few hours before feeding them. There are a number of fish foods available eg. Live food, flake pellets, algae wafers and frozen foods. Feed your fish once or twice a day, offering just enough food so that it is eaten within 2 minutes. Start with a small amount and then add a little more if it is eaten quickly. Too much food will pollute the water so make sure any leftover food is scooped from the tank after feeding.  

A healthy tank for healthier fish: When looking after your fish, little and often is the best practice. Your cleaning plan will depend on the type of tank you have and also what species of fish you have living in.

As a general rule you should aim for the following:
Daily: Check the filter is working correctly.
Weekly: 

Clean algae from the glass

Carry out a water change of between 10% and 30% of the tank’s volume (depending on how many fish you have)

Clean filter parts & filter media thoroughly in tank water (never use tap water, as this kills beneficial bacteria)

Replace filter media as recommended by the manufacturer

For aquariums up to 68 litres, change the filter cartridge every 28 days

Replacement cartridge packs are available (sold separately)

Air pumps are a great addition to your set up, they help to circulate water around your tank, allowing CO2 to be released from the waters surface and oxygenating your aquarium to help fish and plant life thrive. Not only are they ideal for the health of your fish and your aquarium, they are perfect for adding depth and creating a decorative effect.
