The yellowtail damselfish is also known by its binomial name Chrysiptera parasema. It is a very popular species of saltwater fish that is also kept in an aquarium as pets. The yellowtail blue damselfish are native to the reefs of the Indo-Pacific and are mostly found around the countries like Japan, the Philippines, and Australian regions.
These fish are known to be one of the most common fishes kept as a pet in saltwater aquariums and community tanks because they are very tolerant fish and are inexpensive and hardy fish. However, these fishes have special requirements like specific temperature, minimum tank size, pH levels, optimal care level, so their temperament remains stable enough to be kept as a pet. One of the most important requirements is a high level of nitrates in the tank, and this is a problem for their tank mates as most fishes cannot tolerate high levels of nitrate, even if they could for some time, these tank mates can end up dying. Other than that, they required 20 gal (75.7 L) of minimum tank size to live.
The damselfish yellowtail is also known to be aggressive. You can say that they are semi-aggressive marine fish because they tend to show very aggressive territorial behavior towards other small groups. They will ensure that your aquarium is not a peaceful one if you introduce newer fish to the tank.

Yellowtail blue damselfish are the least compatible fish as they show a semi-aggressive behavior towards other species. Suppose they are kept with their own kind or other subspecies of damselfish that show similar aggressive behavior. In that case, they are good to go, and your tank can hopefully have a peaceful ambiance. Also, ensure that you place these fish in small groups not to show a lot of aggression. The most compatible fishes kept with these semi-aggressive species are dottyback fish, tangs, six-line wrasse fish, clownfish, and other species of damselfish.
A yellow-tail blue damselfish's life span and life cycle can last for up to 2-6 years in the wild. These fish can also live more in captivity for around 15 years of age if it is kept in an ideal environment. You have to feed them proper food also to ensure that they do not fall ill. Also, ensure that the temperature in the tank is optimum to prolong their life cycle.
The yellow-tail blue damselfish becomes more aggressive during the breeding period. The female fish chooses the male by visiting his territory, and when she finds the perfect one, she stops swimming in front of this male and displays a light ring around her eyes. After the reproduction process is done, the job of the males is to guard their eggs and nothing more, while females find the nesting site for which they are very picky and then lay eggs where they like to. They then start the feeding process after the eggs hatch.
When in captivity, the process is very easy as the pair comes together, and after eggs are laid, they hatch in a couple of hours or in one and a half days. It is better to keep the lights off in the aquarium. After that, when the larvae emerge, they go into hiding. At this stage, you can try to give them as much light as you can for them to survive. In around 15-40 days, you can see that your larvae become full-grown adult fish and are not juveniles anymore.
The half-blue damselfish are categorized as Least Concern by the IUCN Red List, meaning that they will not be vulnerable anytime soon.

The adult does not have a specific name for the females and males. They are referred to as male yellowtail damsels and female yellowtail damsels.
Like every other offspring of marine fishes, the baby yellowtail damsel is also known as fry. When the fry is young and has just emerged from the eggs, they are very shy and stay in hiding for the time being. The parents feed them and take care of them until they are old enough to survive independently.

Yellowtails can change the color of their body as these fish contain chromatophores, which are the cells that produce colors, which can help them change color in response to stimuli. Usually, yellowtails change color and turn darker than the usual intense blue when these fish are stressed out. The change in color helps them conserve their energy easily.
Although yellowtails are aggressive, they like to live with peaceful tank mates to ensure that those fishes are not notorious with them.
