The Purpleback Pseudochromis, also known as Diadem Dottyback or Diadem Pseudochromis, is primarily yellow with a purple stripe running the length of the body along the dorsal fin. It is quite famous for its ability to consume and control bristle worms in the aquarium. The Purpleback Pseudochromis needs about 3+ hours for acclimation and is considered as a very good reef or community fish. It is very easy to maintain and is considered as one of the hardiest fish. The Purpleback Pseudochromis is great for reef tanks and makes a great addition to it. This little beauty can be aggressive towards other smaller fishes in the tank, hence should be kept singly and should not be mixed with other Basslets or Dottybacks. The Purpleback Pseudochromis should be provided with ample rock work, and small caves of the coral reef where it loves to inhabit, preferably in larger tanks. If you wish to have a group of this little beauty in your mini tank, introduce all the Purpleback Pseudochromis fishes at the same time so that they get along well with each other at the time of acclimatizing. The Purpleback Pseudochromis can be fed with frozen foods such as Mysis shrimp or Brine shrimp which are readily accepted by this beautiful fish. The Purpleback Pseudochromis looks stunning in any tank with their dramatic coloration. It is capable of changing sex, and when the eggs are laid, the male is known to carry these eggs on its mouth to keep it aerated.
