In the wild these fish are typically found in small shoals that allow the fish to make the most of their pin-stripe pattern to help protect them from predators. They use the stripes and the false eye-spot on their tails to confuse any potential predators.

These stunning little fish is an ideal candidate for smaller tanks & larger tanks alike. They are happy to be kept singularly, in small groups or in a large shoal. They will not bother any of your other inhabitants and should be considered reef safe.

You may have noticed the large eyes these fish have, this is because they are nocturnal. This doesn’t mean they will only come out at night, mine are out all through the day, but they are also out and active after dark.
