He kind of already is! Hmm... the exercise is good for him, the pellets are not. What a connundrum!
Here's a random question for you - when I was looking at these fish on Youtube, everyone was feeding them WORMS! Are you going to go that route eventually? Or just stick with pellets? Just curious. Worms are *blegh* and since he takes the pellets altogether too well, I guess there isn't a NEED. But, you know, I wonder things! You still feeding him every other day? Any changes in that adorable tummy? I kind of LIKE the chub, you know!
