The Four Lined Wrasse (Pseudocheilinus tetrataenia) is a smaller species which does better in a less belligerent tank, but may act aggressively toward towards more peaceful wrasses and other small fish. Given the right cover, it will spend a lot of its time hiding and foraging for small snails, worms and crustaceans in live rock.
