The Mertensii Butterflyfish, also known as the Orangetail Butterflyfish, or Crowned Pearlyscale Butterflyfish, is a blue silver coloration with black margins on its body scales. This gives a crisscross pattern and pearly sheen. Most of its posterior is orange and it has a silver-edged black stripe through the eye.
It may reside in a 400 litters or larger aquarium provided that it is well-maintained and relatively peaceful. It may be kept with other Butterflyfish if they are introduced to the tank at the same time. The Mertensii Butterfly is not considered reef safe.
The diet of the Mertensii Butterflyfish should include various meaty preparations. This species eats glass anemones (Aiptasia). But occasionally one finds an individual fish which refuses to eat them.
