  • Description
  • Blue Damselfish are stunning small fish that make great fish for beginner aquarists. Blue Damselfish look different depending on their sex. Females are fully electric blue, while males have orange on their tales with an electric blue body.

    Blue Damselfish reach a maximum size of around 3 inches and need to be kept in a tank that is at least 29 gallons in size. Blue Damselfish are reef safe and will not bother coral or inverts found in reef tanks. Blue Damselfish are somewhat aggressive and need larger tanks if keeping multiple Blue Damselfish in one tank to reduce the chance of aggression over territory. Blue Damselfish have also been witnessed to be aggressive to other non-damsel additions to the tank after they get established.

    Blue Damselfish do best when there is lots of live rock for them to hide in. If a Blue Damselfish feels threatened, it will go into the rock work and change color to almost black. When they no longer feel threatened, they will come out of the rock and regain their brilliant blue coloration.

    Blue Damselfish are omnivores and require a diet both rich in meaty and green foods. They are very aggressive eaters and foods such as mysis and brine shrimp, frozen food and high quality pellet and flake foods will help keep your Blue Damselfish healthy and thriving.
