Mimic Eibli Tang

Mimic Eibli Tang juveniles look like the Eibli Angelfish (Centropyge eibli). This is a form of Batesian mimicry which is a survival mechanism. It is thought that the dwarf angelfish is less appetizing to would be predators and the Mimic Eibli Tang has evolved to mimic this look to help avoid predation. It is an amazing occurrence in nature, nonetheless.
The Mimic Eibli Tang gets to about 10 inches when fully grown and needs at least a 120 gallon (454 liters) aquarium with lots of open swimming space. Keep the tank highly oxygenated with lots of turbulent water flows. They are often found in lagoons and near seaward reefs at various depths of 6 to 85 feet (2 to 26 meters). As they mature, they lose the juvenile markings and start to turn a more drab light brown or gray with darker gray fins. Juveniles are definitely more attractive looking and fetch higher price tags than adults.
They need to be fed primarily algae or nori (dried seaweed) along with a high quality pellet food. You can supplement their diet with defrosted foods like Rod's Herbivore Blend or similar. As with all fish purchases, make sure they are eating at the store before bringing them home. Sometimes specimens that are too small (less than 2 inches) are hard to get eating. Make sure they show an aggressive feeding response when food hits the water at the store. This will help ensure that you bring home a healthy fish to place in your quarantine tank for a few weeks before introduction into your display tank.
Avoid keeping them with other tangs, especially conspecifics. If you do plan on keeping them with multiple tang species try to introduce them all at once. They should do well with most other fish species. Some LPS coral keepers have reported seeing them nip at polyps so use caution if you have a reef tank setup. You can buy them locally or online for anywhere from $40 to $60 or so.

More Tang & Surgeonfish Profiles
Pacific Sailfin Tang
Looks very similar to the Red Sea Sailfin, but the one collected in the Pacific doesn't have as many spots. Lots of marine algae and a very large tank are some care requirements. Check the profile for more care information.
Powder Blue Tang
Often sought after due to their beauty, the Powder Blue Tangs will quickly leave the uninformed hobbyist singing the blues if they are not prepared to care for this tang.
Powder Brown Tang
Adapts to the aquarium much better than the Powder Blue Tang.
