The Yellow-Breasted Dottyback (Pseudochromis coccinicauda) can be found among reefs and rocky outcroppings in the Indo-Pacific Ocean. They have a beige body with a yellow or orange caudal fin. Mature males may develop a yellow chest. They reach a maximum size of 3 inches, do well singly, and can be housed in an aquarium with at least 30 gallons with plenty of live rock. Lids are recommended, as dottybacks can jump through small openings. They may be semi-aggressive towards tankmates, so they should be housed with fish of similar temperament. They are carnivorous and require a meaty diet, typically consisting of mysis, krill or brine.
