They live in the warmer waters of the Pacific Ocean and Indian Ocean. There are no clownfish in the Caribbean. The spawning season of the clownfish, a time when they breed, is year round in tropical waters. Males attract the females by courting. Courting behaviours include chasing, biting and extending fins. Clownfish lay their eggs in batches on coral, rock or next to the sea anemone that they call home. The male clownfish will build a nest on the rock or coral near the anemone in order to be provided with protection from predators.
Breeding starts by the male chasing the female to the nest where the eggs are released. One hundred to one thousand eggs are laid.
The male clownfish guards and protects the eggs until they hatch. They hatch within 4 to 5 days. In a group of clownfish, there is a strict hierarchy of dominance. The largest and most aggressive female is found at the top. Only two clownfish, a male and a female, in a group reproduce through external fertilization. The clownfish are hermaphrodites, meaning that they develop into males first, and when they mature, they become females.
Also, as mentioned earlier, more than one clownfish is able to live in a sea anemone. If the female clownfish is removed from the group, such as by death, one of the largest and most dominant males would become a female.
The rest of the remaining males will move up a rank on the hierarchy. Biological Profiles.

Because of the protection afforded them by their host anemones, common clownfish have few predators, but they are at risk of predation when they leave the anemone to feed. Like all clownfishes, this species changes sex throughout its lifetime. Sex change is not particularly rare, but most species change from female to male. The clownfishes change from male to female. All individuals hatch as males and eventually join groups of a few individuals living together in an anemone.
The largest individual of each group is the only female, and she and the largest male are the only two that reproduce. The large, dominant female lays her eggs on the reef surface, and the male fertilizes them.
Together, they guard the nest from egg predators until they hatch. If anything happens to the female, the reproductive male changes sex, becoming the dominant female. This matters because the frequency is going to affect the quantity. If you feed ordinary fish too many times a day, you will ultimately harm them due to overfeeding. So, where do clownfish fall in this equation? The answer is both straightforward and complicated. In most cases, you are encouraged to feed your clownfish twice a day.
Most fish experts you encounter are going to provide this same estimation. However, that applies explicitly to adult fish that have already reached their full size. Juveniles have more vigorous appetites since they are still growing. As such, they need all the nutrients you can give them to maintain their health as they mature. For the best results, you need to feed juvenile clownfish times a day. They need more food than ordinary adult clownfish, which is why they should be fed three or four times a day.
Fish owners love clownfish because they are not picky eaters. They will eat almost anything you add to their tank. Unfortunately, they will also keep eating if you keep adding food to their tank. They have no significant self control in this department. It is up to you to ensure that you do not feed them more than might be healthy. The duration is just as important. Even if you only feed your fish once a day, you still ran the risk of overfeeding them by adding too much food to their tank.
Give your clownfish food in quantities they can finish within two or three minutes. You can bring that figure down to one minute, depending on how frequently you feed them. You can also raise it to five minutes if you only feed them once a day. Ensure that they have eaten every morsel of food you have offered them within the set duration.
If they fail in this endeavor, then you have probably given them too much food. For instance, if 3 minutes is your chosen duration, keep adjusting the quantities until you are giving them food in amounts they can completely devour in 3 minutes. If they have food leftover after that period expires, you are still giving them too much. Clownfish are omnivores. In other words, they have an affinity for both animal and plant matter. Out in nature, they will eat everything from algae to fish eggs and larvae.
They have also been known to eat crustaceans and the tentacles of anemones. Do not permit their diet to become stale. Try to add some variety. While they will appreciate live foods, throw frozen foods into the mix every once in a while, not to mention freeze-dried foods, flakes, and pellets, etc.
That includes vegetables like Nori and Spinach. Keep things interesting by varying their diet. While the general answer is yes, I also mentioned there a few feeding techniques that would prevent water pollution. Seaweed, and Nori, in particular, are incredibly nutritious for clownfish. It is never a good idea to feed an adult fish more than four times a day. However, as was mentioned above, things are not so straightforward with clownfish.
