Nemo the fish

Clown fish are also called anemone fish because they live their entire lives in an anemone, which becomes their protector from predators. After the premiere of the film Finding Nemo, the popularity of the clown fish increased dramatically. These fish are often found in marine aquariums, mainly due to their recognition and attractiveness, as well as their relatively low breeding requirements.
1

There are 30 species of clown fish. Twenty-nine belong to the genus Amphiprion and one to Premnas.

2

They often live in a symbiotic anemone, which provides them with protection.

However, this is not a one-way beneficial cooperation, since the clownfish living in the anemone feed it with their excrement and lure larger fish into its vicinity so that it can paralyze and eat them. They also protect it from predators and parasites.
3

Most species of clownfish have an orange body with one or more white stripes.

The stripes are usually outlined with a black line.
4

The most popular species of clownfish is Amphiprion ocellaris, which is widely kept in reef aquariums around the world.

Perhaps this is the most popular sea fish. Here are some details about the Ocellaris anemonefish:

  • they reach 11 cm in body length
  • live in the eastern part of the Indian Ocean and the western part of the Pacific Ocean, sometimes they can be found off the coast of Japan and Australia,
  • in the famous cartoon Nemo there was a representative of this species, Amphiprion Ocellaris.

5

Clownfish are omnivores.

They usually feed on the remains of the anemone in which they live, but can also feed on zooplankton, algae, copepods and tunicate larvae. Sometimes they bite off the tentacles of the anemone they live on.
6

These are very hierarchical animals.

At the top of the hierarchy is the most aggressive and largest female. The female mates with the alpha male and spawns only with him.
7

They are monogamous.

A clownfish colony consists of one female, a reproductive male, and supporting young males. Only the reproductive male takes part in reproduction.
8

Like most fish, clownfish reproduce by ovipositor.

For reproduction, the male prepares and cleans a flat stone, on which the female lays 600 to 1500 eggs.
9

The male takes care of the nest and fry.

After copulation, he is responsible for caring for the nest. It removes dead eggs with its mouth and uses its pectoral fins to circulate water to ensure the eggs have enough oxygen.
10

Young clownfish hatch 6–10 days after the eggs are laid.

This usually happens at night, 2 hours after dusk.
11

Clownfish are the most commonly traded saltwater fish.

Clownfish are easy to breed in captivity, so every year fewer and fewer of them are caught in ocean waters. However, quite a large number of them still come from ocean fishing, which contributes to the damage and destruction of coral reefs.
12

The average lifespan of a clownfish in the wild is between 10 and 13 years.

However, there are species that live much longer, such as Amphiprion percula, which can live up to 30 years in captivity.
13

All clownfish are born male.

In adulthood, they can become females. This happens, for example, when the dominant female in a group is killed.
14

When clownfish lack anemones, they may feed on soft corals or large polyps of stony corals.
