When setting up a goldfish tank for the first time, it’s important to choose a suitable substrate for the base. But what is the best substrate for goldfish?
The answer is that there isn’t just one good substrate for goldfish or a single choice of the ‘best’ substrate in all situations.
Your choice of substrate will be influenced by a number of factors, which are specific to your tank. These include the type of goldfish you are keeping, whether you will be keeping live plants, whether you’re happy for those plants to be in pots, and your personal preference for how the tank will look.
