Yellow coris, they stay small, brilliant color, swim all day but sand sleep at night, eat pests in the tank.This is a large thread, so I'm sorry if this has already been discussed here, but does anyone have recommendations for a Wrasse that would do well and be comfortable in a 30L (30 gallon-36" long) tank? Looking for something with a peaceful demeanor if possible and I'm still relatively new to the hobby, so ease of care is a plus
