my favorite fish. Hello. everybody. Do you know what my favorite fish is? it's unicorn fish they are so unique. they have this little horn on their head. and it makes them look a knight without making them look so defensive. actually they are kinda cute also. I like them. the first time I saw them was at the under water world in singapore. and I was like. " hey, mary , I say an unicorn " they are commonly found in coral reefs, patch reef, and rocky tropical areas of the Indian and Pacific Oceans and the Red Sea. Some are found near Hawaii and Japan. Luckly I am living on the island of oahu. anybody up for a free diving. ? cheerio.
