Description

Left undisturbed, algae would soon blanket the coral in a carpet of green and the coral would soon die. To the rescue come algae-eaters like the Unicorn-fish. The mouth of this fish (like other Surgeon-fishes) is perfectly designed to carefully remove the algae from coral while leaving the coral intact. Its fine row of sharp, small teeth makes short work of the algae. The horn-like appendage between the eyes begins growing when a young fish reaches about 5 in (13 cm) in length, and tends to be a little bigger on males. The Unicorn-fish does not use its horn for defense, but rather its sharp tail spines. Biologists are unsure of the purpose of the horn. This fish has the amazing ability to change its color almost instantly depending on its environment and its mood.
