List of Purple Fish

Coastal reefs, mangroves and home aquariums all host a surprising variety of hues, and purple shows up more often than you might expect. Spotting a purple fish while snorkeling or scrolling species lists can reveal interesting stories about habitat, behavior and diet.

There are 20 purple fish, ranging from Betta to Sunrise Dottyback; details (Scientific name,Size (cm),Range) you’ll find below.

Can I keep purple fish in a home aquarium?

Many purple species are suitable for tanks, but needs vary — freshwater Bettas differ from saltwater dottybacks in water chemistry, tank size and diet. Check the Scientific name and Range for each entry below to match habitat and care requirements before buying.

How can I tell similar purple species apart?

Look beyond color: compare Scientific name,Size (cm),Range, fin shapes, and patterning, and consult photos or regional guides. Size and natural range are especially reliable for narrowing down species when hues overlap.
