I took some liberties, the holefish has a very similar body structure as the peeper (minus the hole of course), so i thought it fit more in the peeper family. it could have evolved convergently though. With the eyeye I see hardly any comparable features to the peeper, and yes it does go out of the cannon, but it seems more logical that a one eyed creature is related to other one eyed creatures, rather than it being in a family with all other creatures having two eyes.
