I agree with rivercats on his idea to figure out the culprit.
I still think it would be the tigers, if not then them the gourami and lastly the angle. If the angle were larger than perhaps I would feel he would be the main cause but by your description he's fairly small and to my knowledge their aggression will surface more as they mature then with juveniles. Though anything is possible. I have one in my tank and he's about 2 inches from head to tail and he's such a slow poke. I couldn't picture him chasing down guppies or tetras. lol. Even my sunset gourami is faster than him. Maybe he is just lazy. lol
