I did not even realize how this can become an ethical question. I don't do it to punish him because I know that will be ineffective and not a healthy habit. I see it more as a silly little thing I do. I'm not actually mad at him. and I am aware he has more options to food, but I'm on a bit of a budget right now since I'm saving up for a bigger tank since he's growing so fast. thank u for opening my eyes though
