The Talbot's Damselfish, also known as Talbot's Demoiselle, has an attractive canary yellow head and a bright blue body. They are a very active species that maintains a small size in the aquarium, but can become territorial as it ages.
It is considered semi-aggressive and should be housed in a 30 gallon or larger aquarium. It will need adequate hiding places to develop territories and to avoid other aggressive tank mates.
The diet should include a variety of meaty foods, herbivore preparations, and flaked foods.
