What fish tank size do I need?

To ensure your fish are healthy and thriving, you will need to use one gallon of water per inch of fish. So per inch of fish that you have or would like to purchase, your tank should have or hold one gallon of water.

What happens if a fish tank is too small?

Having a fish tank that is too small can cause several issues, these include your fish becoming aggressive and having stunted growth. Both of these issues can lead to your fish dying.

Which fish tank material is best?

Fish tanks are usually made from two different types of materials - glass and acrylic. There's been plenty of debate over which is better, and the best material for you will be the one that suits your needs the most.

Glass:

  • Cheaper
  • Scratch-resistant
  • Will not yellow over time

Acrylic:

  • Lighter
  • Impact-resistant
  • An array of shapes and sizes  

If you're looking for the most budget-friendly material, then we recommend you go with glass. However, if it's variety you're after and more lightweight material, then you should consider purchasing an acrylic fish tank.
