What Is A Clownfish?

Clownfish” is a common name used to refer to any of the thirty recognized species within the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized: one in the genus Premnas, while the remaining are in the genus Amphiprion.

Factors Affect Your Clownfish Life Expectancy

Most clownfish will have different lifespans. Some will die earlier while others live significantly longer. Sometimes, even when you do everything right it’s still not enough to save your fish. It’s ok – It’s the way nature works. 

However, there are still things you can do to make your fish’s life better. Ways that will definitely prolong its life.


Feeding your Clownfish a healthy diet will improve their overall health and lead to an increase in life expectancy. Make sure that you feed your clowns well, and on a frequent basis.

Genetics plays a big role in the overall health of the fish, too. Today, there are many new designer varieties of saltwater fish entering aquariums.

I suspect some of these types of clownfish won’t live long compared to some natural types. However, most of these claims are just assumptions. The best thing to do before you buy a clownfish is checked that it’s from a reputable breeder who knows his stuff. 


One of the most common reasons for a short life span in captivity is poor tank conditions. It’s also worth mentioning that inappropriate tank size can be an issue. Smaller tanks are often harder to maintain and typically offer poor living conditions for fish. You may not need a large tank: around 30 gallons is a good size to start.

One of the myths people have about clownfish is that they need to be kept with an anemone in order to survive. Contrary to what you might think, It survives just fine without anemone. Skipping the anemone means you get to avoid its challenging care and high lighting needs. However, having one available does make for a nice touch. If you’re able to provide anemones, the addition of these underwater plants makes for a beautiful set-up.
