Looks great. So often are you feeding, every day?
You know what's weird? Mine has really slowed down on the eating in the last month. Seems to be doing OK, was looking at some pictures from a few months ago and he's put on a lot of weight, so I guess all is well. But is definitely eating less. Up until a month ago it was every day, now it's more like every other day and even then sometimes it will just be one krill. I wonder if he's getting bored of that food but he shows no interest in silversides.
Although on the other hand where did you score those small silversides? Everytime I ask for small silversides at a LFS they pretty much reply with "here you go, here are your enormous silversides, now please be gone with you and your requests for small silversides".
I SWEAR I used to be able to buy these little small silverside things ten years ago, now everytime I find them they are like bait smelts and minimum 3" long. Weird.
