I have a 13 inch and 7 in wolfs in with baracudas...MBU puffer, and 5 dovii (5-9 inches). I put in 100 large feeders 2x/month. The Baracuda eats about 90 of them in 3 days but the Wolfs seem to love cichlid sticks as they come to the top and leap at them as opposed to a more gentle grab from the Dovii's.
