A 55 gallon fish tank might seem like overkill, but there are many instances where you might require one. For example, if you’re serious about keeping fish, then you’ll definitely need an aquarium which is around the size of 55 gallons (or at least around that!). These plastic and glass tanks are available in a variety of dimensions, shapes and materials, but they’re all 55 gallon, and they’re all for fish! There is also a brief guide which shows you how to set up and maintain your 55 gallon tank once you get it. Here is a quick run through of the post and the dimensions of the tanks:

Marineland 55 gallon long aquarium, 50.1 inch length

This is a very affordable tank (considering it is 55 gallons!), and is great for anyone who doesn’t need anything too fancy. It’s made from glass, is easy to clean and comes complete with a few added extras:

  • LED Lighting
  • Penguin 350 BIO-Wheel Power Filter and Rite Size filter cartridge
  • Fish net
  • Thermometer
  • Fish food
  • Water care samples
  • Set up guide

So as you can see, you get a lot of bang for your buck with this tank! The Penguin bio-wheel filter provides quiet but very effective water flow, which helps to make the water safe for fish. The kit also come with fish net (so you can catch your fish if you need to!), thermometer (so you can keep the tank at a safe temperature), food and water care samples (always good!) and set up guide (so you know what you’re doing!).

The lighting is integrated securely into the hood, and although they don’t have a timer option, but instead a 3-way manual switch (white, off, blue) that correspond to 3 different lighting modes.

55 Gallon Clear for Life Hexagon Aquarium 

I think we’ve saved the best until last here! Sold by PetSmart, this hexagon aquarium is the perfect home for any larger species of fish that you may look after. At 55 gallons, there’s more than enough room in this tank to hold larger fish. We’re huge fans of the design, and think that the hexagon shape is perfect for fish who like a bit of privacy. What many people don’t talk about is how important corners are for fish – they love hiding in them! If you fill this tank with decorations and plants, then they’ll be able to hide in any corner they want. Perfect for shy fish like Bettas!
