Fun Lemon Damsel Facts For Kids

The lemon damsel (Pomacentrus moluccensis) is a type of bright yellow, marine reef fish belonging to the Pomacentridae family, which contains damselfish and clownfish.

They can be found living in the western Pacific Ocean, among clearwater lagoons and reef corals. They are highly sought after as pets due to their dazzling color, making them very common in the fish breeding industry.

These fish are quite small, reaching an average length of 3.5 in (9 cm) and can be distinguished from other yellow fish by the presence of a distinct orange spot near their pectoral fins.

Despite the aggressive reputation of damselfish, the lemon damselfish is not as bad as it is made out to be and can be conditioned to get along very well with its aquarium mates. They love to dart and hide among the tank as they are used to living among the reef corals.

Swimming among the coral reefs, these fish can communicate with each other using a variety of chemical signals.

Yellow damselfish can release chemicals called pheromones to communicate with other members of their own species, and allelochemicals to communicate with other species. They can relay a range of messages such as the intent to mate, presence of food or intruders, or distress.

They also communicate through gestures, especially in the breeding period where the male performs a high energy 'signal jump' to woo the female, rising up water columns, and swimming down rapidly.

No, these fish are not dangerous to humans. They have been labeled as semi-aggressive and are only known to be aggressive towards members of their own species, as well as towards their tank mates at times. Taking the appropriate measures can help to curb their moody temperament and help them mingle with their cohabitants.

Would they make a good pet?

These fish are very attractive and their bright yellow scales will definitely brighten the atmosphere in any tank.

However, there are certain protocols that must be followed when introducing them to a multi-species aquarium to ensure that they stay on their best behavior.

They must not be housed exclusively with fish smaller than them because they can be bullies at times. They can also be quite aggressive towards members of their own species, so plenty of hiding places must be provided for them to escape to.

In order to prevent them from becoming too territorial, they must always be added into the aquarium as late as possible, so that they mingle with their tank mates and do not claim any area for themselves.

Did you know...

Damselfish are known to be quite aggressive, however, the level of aggressiveness varies from species to species. The most aggressive type of marine damselfish is said to be the white-spotted devil (Plectroglyphidodon lacrymatus) which will bite and attack anything that comes close. A large school of these fish can be quite dangerous indeed.

Do damsels eat coral?

Though damselfish do not directly eat corals, they have been known to contribute to the breakdown of coral reefs by 'farming' algae on them in excess.

Due to the overfishing of their predators, the damselfish population is thriving among branching corals. These fish use a large area of the reef to tend to their farms which they use for breeding and feeding.

However, this leads to further stress on the coral, especially head corals, which leads to further reef deterioration on top of global warming, water pollution, and coral hunting.
