context_page_description: The following list of marine aquarium fish species commonly available in the aquarium trade is not a completely comprehensive list; certain rare specimens may available commercially yet not be listed here. A brief section on each, with a link to the page about the particular species is provided along with references for further information.
context_section_description: All Damselfish can be considered reef-safe, sometimes excluding larger, more aggressive Dascyllus varieties. Some Damselfish will host in anemones like clownfish. Most Damselfish are aggressive and difficult to catch once you put them in an aquarium.
  Damselfish change gender as they grow larger and older. Small damselfish are ungendered. Eventually, they become males if no males prevent them from doing so. One or sometimes two males live with a female and guard over the eggs. Females are the largest fish and dominant over the males and juveniles. They will not allow other females into an area they have claimed as their territory without a fight. They may not allow new males or juveniles, either. Aggression increases with each change.
