Trainer Clarry Conners has been fined $500 for not reporting a treatment given to Vaniloquio three days before the horse's win at Hawkesbury.
Conners gave the horse the common calming medication acepromazine on August 31 and Vaniloquio won a benchmark handicap on September 3.
Conners was fined $400 in 2014 for failing to maintain complete treatment records.
