Yeah young Cichlid have teeth. My 2 1/2 inch Convict Cichlid has teeth.
Their lips aren’t exactly soft so it takes time to see visible damage. But you can see it pretty often in pairs after lip locking for an extended period of time.It is a wonder they don't do more damage to each other when they lip lock seen many video's of various cichlids lip locking with hardly any damage after a lip locking duel.
