Fire urchins are undeniably one of the most stunning of the urchins, predominantly red with vertical lines of electric blue spots.

Fire urchins also known as blue spot urchins are predominantly algae eating inverts but will also scavenge detritus and meaty morsels when the opportunity arises. 

Urchins have a voracious appetite so are excellent at helping you control algae in the aquarium. Keep urchins well fed with natural algae or sheets of dried algae and occasional chunks of meaty foods and they should make fine additions to a reef. 

Be aware that fire urchins have a venomous sting similar to that of a bee sting.
