Does your fish tank smell? If so, there are several possible reasons why. In general, marine fish tanks should be odour-free, except perhaps the smell of the ocean, so if you find that you can smell an unusual or unpleasant odour coming from your tank then you may have a problem that needs sorting out quickly.

Just like humans, fish sometimes get ill. There are all sorts of diseases that can affect the inhabitants of your marine aquarium, and some are more dangerous than others.

In today's blog post, we're going to look at some of the most common marine fish diseases and the tell-tale symptoms that give them away. When it comes to treating sick fish, different diseases require different approaches, but remember the old saying: an ounce of prevention is worth a pound of cure. Keeping your tank clean and ensuring that your filter remains in good working order will give your fish the best possible chance of staying healthy and disease-free.
