I gave him his feeder guppies today, and as I was watching him pick them off... he took off after one, and slammed his nose right into the glass pretty hard. He seemed to be a little discouraged after that... lol I shouldn't laugh, because that had to have hurt.. but it really was funny. He even shook his head afterwards as if to shake it off. I'm horrible..
From a sometimes overeager boxer I have to say I know what that feels like . Maybe he'll think a little more next time and learn from the boo boo, unless his melon got shaken up too bad
