Pseudojuloides Wrasse should be added to a well established aquarium with plenty of swimroom. Provide plenty of rockwork with caves and crevices for hiding. A deep sandy bottom should also be provided as Pseudojuloides Wrasse are burrowers, they bury themselves in the sand at night and if they are frightened. Pseudojuloides can be kept with other peaceful tank mates. Pseudojuloides Wrasse may not eat readily when first introduced to the aquarium. If seeing an unwilliness to eat add fortified live mysis or Brine shrimp to their carnivorous diet, fed multiple times daily. Pseudojuloides are not reef safe and will prey on hard shelled invertebrates. May see male and female color differences. Wrasse are hermaphrodites meaning they start as juveniles/females but at some point in their life may turn into a male. Provide an aquarium with a tight fitting lid as they may jump. The Decolores Wrasse are also sometimes known as the Severn's Pencil Wrasse. Occasionally seen in the aquarium trade. Color may vary depending on maturity of the fish. Females are an overall pink color while malea are yellow with a large black spot the front of its body, two horizontal blue irregular stripes on the front of its body and blue and black on its tail lobes. Decolores Wrasse can grow to almost 3". We recommend a minimum aquarium size of 75 gallons or larger for this species.
