I Agree with Peter above.
The Leopard bush fish (Ctenopoma acutirostre) are very peaceful fish that only bother fish they consider small enough to be on the menu.The problem is like Peter has already pointed out the eventual size,an aduly Motoro. leo or Hen for example would over power it, will be fine for a while till the ray reaches a 20-25cm disc, these climbing perch are not the most palatable fish,very hard scaled with a rigid body.
