Hammer coral is a must have species of coral for your reef aquarium. They come in a variety of colors and add lots of life and movement to your tank.
Hammer corals come in three variations of growth type. Wall type, branching type and a large branching semi wall type. They are aggressive corals and should be given room to stretch. Their tentacles will hurt or kill other corals they come into contact with.
Hammer corals do well in medium flow and medium light. Too little flow and they are unable to clean themselves and will become prone to bacterial infections. Angel fish in your aquarium are likely to pick on hammer corals. Hammer corals main predators are a large flat worm that live on the base and slowly eat them.
