Do Clownfish Need Anemones: The Interesting Significant Relationship

Clownfish and anemones are typically found living in close proximity to one another. This is because clownfish need anemones to provide for their necessary needs, and anemones need clownfish to keep them clean.

Clownfish need anemones to get their food, and without them, they will starve. Some clownfish that live in reefs without anemones still attach themselves to rocks or coral with their tentacles, so they can get food that way. A clownfish that is attached to its anemone will have a better chance of finding more food. Since many clownfish can eat shrimps and crabs, in nature there should still be plenty for them to do so they won’t starve.

Why Don’t Clownfish Get Stung by Anemones?

Clownfish and anemones evolved together and have a mutualistic relationship. The anemone provides the clownfish with a place to live and food, while the clownfish defends the anemone from predators.

Clownfishes usually swim in circles around their anemones so any stingers on the tentacles will hit themselves instead of their host fish.

Light Conditions

Clownfish are a type of fish that need anemones to live in light conditions that are similar to their natural environment. Clownfish can’t produce their own light and need an anemone to provide them with the necessary light for photosynthesis. Without an anemone, clownfish would be unable to survive in open water.


Anemones and corals should be placed in the Clownfish tank in an area with enough room to expand. The aquarium should also have soft, living rocks for them to hide among.

Compatibility is important when choosing a fish to keep in an aquarium because it can affect the overall health and well-being of the tank.

Size of Aquarium

Aquarium size for clownfish is typically around 10 to 20 gallons but can vary depending on the species of clownfish. A small aquarium will not be able to provide the anemones and clownfish with enough room to swim and explore, while a large aquarium will mean that the Clownfish will be crowded and may not get the attention they need. It is best to consult with an expert when choosing an aquarium size for your clownfish, as their needs vary greatly depending on their size.


Clownfish are omnivorous fish and as such, they require a diet that is high in plant material and live food. In the wild, clownfish will feed on algae, plants, and small invertebrates. In captivity, clownfish can be fed a variety of foods including flakes, pellets, live and frozen food. Clownfish are herbivores and rely on anemones to feed them.
