My scool of cleaners are all great! I love how the dojos can always get a snack my cleaning a little, the horsehead loach actually takes the gravel inside its mouth cycles it then spits it out the gills. The rapheal is more of a looker. If he has 2 caves. One shared with the small synodontis, one shared with the dojos. you can always see the tip of his whiskers, and the end of the tail, and are amazed at the size! The yoyos are small enough to clean the bristle on the false plants, and I've always been a fan, because my first fish was a 4" yoyo. the synodontis E. has a great dorsal. the sm. syno. has a great facial exeption.
