Common name: Collector Urchins

Toxopneustidae, commonly known as Collector Urchins or Tuxedo Urchins, are a family of sea urchins notable for their vibrant colors and patterns. They are popular in the reefkeeping hobby for their algae-eating habits, which help maintain clean tank surfaces. Members of this family, like the well-known Tripneustes gratilla, are also appreciated for their interesting behavior and relatively easy care requirements. They are generally peaceful and can coexist with a variety of tank mates, but care should be taken to ensure they have ample space and do not become overpopulated, as they can deplete algal resources quickly.
