I would try some cut-up nightcrawlers depending on it's size, and other live foods possibly ghost shrimp, black worms, or small feeder fish ( preferably not caprid in nature ie goldfish,rosy minnows. Guppies, and other live bearers raised/Qtd ect properly) they appear to have similar diet interests as Aba aba's do. and these all worked well on my aba to get it eating and settled in... once it was settled it was fairly easy to get him to take prepared/frozen foods more readily.
