Got it
Ok no matter what happens, guess this puffer is gonna be all alone, though i MIGHT throw in a few fishes to see its consequences from time to time. Maybe it has something to do with the size, as ppl usually throw in cheaper fishes most of the time as trial. Anyhows, i suspect this puffer isn't exactly taking a liking to me as can be seen by its feeding routine.
1. Throw food in
2. Have a staring game with him (or his back sometimes)
3. Get called to do a chore or something that requires you to leave from his view
4. Return to find the food gone
Go figure that one out
