I have a 13" hoplias malabaricus which I've been feeding progressively larger fish because of the entertainment value and the zeal with which he pursues the larger prey. Last night I fed him a shiner that was about 4-4 1/2" long and he swallowed it eventually. Today I was watching my tank and he let out a few air bubbles before regurgitating the fish, partially digested.
Should I be at all concerned?
