They get more confident around the 6" mark. Again since the wound is rounded it shouldn't be someone with triangular mouths ie: Aro, tilapia. That leaves the senegals which are small and probably stay clear of the gulper or they would have been eaten. Down to two possible culprits the bagarius or poly. I'm guessin the bagarius isn't the culprit since as I've said before aggressive cats seem to go for the flanks and rear of the fish. Plus bein on the small side he would almost definetly go for a rear attack. My Aisan RTC was about 3" and nasty as heck, but would attack larger fish than himself from the rear. That leaves the poly who at that size could do quite a bit of damage if he an the gulper tried to consume the same food. They hunt in the same strata of the tank bottom to mid-water and would easily make a mistake and grab a hold of each other accidently. I'm sayin it was the poly.
This is going to be my easiest post ever....I agree with everthing koltsix said here.
