As a result, a good rule of thumb is to get a fish tank which has one litre of cold water per 0.5cm (excluding tails and fins) of fish. For instance, a 50 litre tank could safely house two 10cm and one 5cm fish. Or, alternatively, you could accommodate six 4cm fish. You could probably squeeze a couple more in, but this will all vary depending on the types of fish you want to keep, alongside other tank components such as plants, lights and filters. If in doubt, bigger is always better. The lighting's pretty good too - you can switch between a Bright Day White, or a Cool Blue Moon lighting - your fish will look incredible and your plants will thrive.
