Just return to see something shocking...
My big gulper trying to eat my small gulper... notice them so near together and taking a closer look...(1st round)to my surprise the big one had it mouth on the right side fin of my smaller gulper so i put my hand in and it gave up but once my hand is out of the water it starting to bite again(2nd round) and my small one defent itself to by try to bite back....
I put my hand in again but this them it will not let go so i end up bring both out of water and it finally let go.
last round, my big gulper bite it tummy and finally i put it a floater for my small gulper.
They are not hungry as both just ate alot yesterday...only wonder if it is some kind of mating style haha like Ray bite.
