Clownfish Behaviour

Clownfish have a symbiotic relationship with sea anemone. Anemonefish has a mucus covering that protects them from the sting of the sea anemone’s tentacles. This mucus prevents them from being harmed and allows clownfish to live in sea anemone that why Anemonefish are usually not eaten by other fish.


Clownfish Fact

There are about 30 different species of anemonefish, of which the clownfish is just one. Other anemonefishes are :

Ocellaris Clownfish Ocellaris Clownfish, Clownfish or False Percula Clownfish. It is very closely related to Orange Clownfish which have narrower black borders on the stripes and fins. They also have a taller anterior dorsal fin and 10 (not 11 dorsal spines). So unless you have a very keen eye and a picture of a ‘real’ clownfish handy it could be difficult to identify Amphiprion ocellaris.

Spinecheek Clownfish

Spinecheek Clownfish, Spined-cheeked Anemonefish, Two Spine-Cheek Anemonefish, Maroon Anemonefish, and Maroon Clownfish are another similar species and they can be recognized by their brown to red body, with 2 pale white bands 1 on either side of the face and a central white stripe running down the spine, making it obvious where the name came from.

Tomato clownfish

Tomato clownfish, Amphiprion frenatus which tends to be dark red (especially juveniles) to black with 1 white sidebar (juveniles may have 2 to 3 narrow bars). These can grow up to 14 cm in length and some varieties have darker coloration including more obscured stripes.

Yellowtail clownfish

Clark’s anemonefish or the Yellowtail clownfish tend to have vivid black, white and yellow stripes, though the exact pattern shows considerable geographical variation. The tail fin is always lighter than the rest of the body and usually, you can see 2 white bands – 1 behind the eye and the other above the anus.

hawkfish, pseudochromis, puffers, tang and other clownfish or wrasse. But don’t put together with Lion fish or Carnivorous fish. If possible, keep with the companion anemone is better.



Clownfish Reproduction

Fascinating ability of the Clownfish is being able to change sex. This Anemonefish Fact makes this fish even more of a rarity. On top of the hierarchy is the reproducing female then the mating male. Below them are a bunch of non-mating males. But, if the female dies, the whole hierarchy gets disrupted. The predominant male then morphs into a female and chooses a partner from the various non-mating males. Clown Fish form a very strong bond with their mates. They lay their eggs in large batches. These eggs are laid on a coral or a rock adjacent to the Anemone. Both the parents then guard these eggs for a span of 3-5 days. Once the eggs are hatched the male may stay to take care of the young till they reach sexual maturity.
