Allen's Damselfish, Pomacentrus alleni

The Allen's Damselfish is a beautifully coloured fish that is reef safe and will make an amazing addition to your marine aquarium. It has a gorgeous blue colour across the majority of its body and features a yellow lower fin which provides a lovely contrast to the blue hue. They thrive best when they are in groups as this will enhance their natural colours and allow them to shine, if they are kept singley then their colours will begin to dull as they will become stressed. These fish are perfect for beginners as they are fairly hardy and don't have any unusual or tricky dietary requirements.
