Help and advice on shopping for: Aquarium Kits & Décor
Which aquarium type is best?
Aquariums come in many shapes and sizes. It's commonly thought that beginner aquarists should choose a smaller tank, but actually the opposite is true. Choosing a larger aquarium provides more stability in the water quality, as well as plenty of room for keeping a variety of fish. We always suggest that you choose the largest aquarium that fits your budget and space.
Our range includes both tropical and coldwater tanks, so you can choose the ideal aquarium for your desired species.

Frequently Asked Questions:
What comes in an aquarium kit?
Kits vary between brands and size. Some feature a display tank and purpose built matching cabinet, others also include essential equipment such as a heater, filtration, and lighting. Check each product description for a full contents list.
Do I need a cabinet for my aquarium?
Aquariums are very heavy when filled with water, so it's important to make sure you have a purpose‐built cabinet or stand to support the weight safely and keep the tank level.
Should I use natural or artificial decorations?
Both decorations come with their own benefits. Using natural decorations can aid water quality, as well as contributing to a vibrant and interesting aquascape full of hardscape like wood, rocks, and live plants. However, artificial decorations are simple to wipe clean, and don't have a risk of bringing pest snails into your tank.
Which substrate is best?
Gravel is the most popular choice as it is simple to clean, especially with a gravel vacuum. However, sand is more practical for bottom-dwelling species. It's always recommended to research the suitable grain size for your species beforehand.
