Giant Damselfish

(Microspathodon dorsalis)

Microspathodon Damselfish should be added to well established aquariums with plenty of room to swim. Plenty of boulder type rock work should be provided along with strong water flow. Microspathodon Damselfish are very aggressive careful planning and consideration should be taken before adding fish to aquariums. They should be housed singly and only be housed with larger, intrusive and more aggressive tank mates. A diet of meaty and algae based foods which includes Spirulina should be provided several times daily.
