There are several species of these very beautiful fish to choose from when deciding which you will put in your aquarium. Some are almost invariably peaceful, while others can be really aggressive. Ask for advice and note the behaviour before you make a purchase.
The Yellow Tailed Anemone fish (amphiprion clarkii) is one of the more readily available species, and will usually settle in to aquarium life easily. The strongly contrasting colour scheme is variable and makes it a popular choice.
Fire Clownfish (amphiprion melanopus) are beautifully contrasted in colour and are usually snapped up when stocks appear. The rich red colour is instantly eye-catching.
