The Beau Gregory Damsel is a very hardy and active fish, and with such beautiful stunning color it makes a great addition to your aquarium. It prefers to hide over the crevices and holes when it is threatened, therefore lots of live rocks are recommended to be kept for them. The Beau Gregory Damsel is somewhat aggressive but if given individual crevices and niche, the aggression decreases. It is a very good choice for a beginner aquarist as it is easy to care and is small in size, thus making it an ideal companion fish for reefs and invertebrates. But as it grows the aggression increases, causing problems with the selection of other species to be added to the aquarium. The Beau Gregory Damsel mainly feeds on flaked and frozen foods, and herbivore preparations. It is probably the bestselling marine fish in the United States. Breeding is possible in captivity if provided with a male and female pair. It seems to be very resistant to most saltwater fish diseases but you still need to take proper precautions and use a quarantine tank before introducing them into your main tank. After they've been in quarantine for two weeks or so and you notice no signs of illness you can acclimate them into your display tank. It is best to keep the Beau Gregory Damsel either singly or in pairs to avoid aggression behavior in a peaceful community aquarium. The Beau Gregory Damsel thrives well in temperature range of 72-78 degree Fahrenheit, and pH value of 8.1 to 8.4.
