What are some really bright, vividly colored, exotic fish?

hi, my art teacher is starting this project on fish to raise awareness about endangered aquayic life. she wants us to make paper mache fish. but the thing is its an art cl so she doesnt want to see all black fish or plain fish. so i wanted to do a fish that has bright vivid colors like oranges and neon purples and yellows and emerald greens. im really into this project because i love the sea and i like looking at fish too but i have no idea what fish i shoul make. any ideas? thanks so much!
