The Mccullochi Dottyback is a stunning addition to my 50-gallon reef tank. The coloration is vivid and the fish is active in open areas. I’ve had it for three months and it’s thriving with the live rock setup. Very rare and beautiful.

First time keeping a dottyback and this one stands out. The male’s red and purple colors are striking. It’s a bit shy at first but settles into open swimming after a week. Needs a large tank, but worth it.
Emma Morrison –
Great color and movement. I noticed the female’s head is purple and tail is yellow-red, which is quite different from the male. The fish is peaceful and doesn’t bother other tank inhabitants.
