I'm looking for some advice, My boy is 215g, he's still a baby. He's eating well, but I'm worried his meals are too small. He's eating rat fuzzy's, but I'm not seeing a bulge. I haven't tried to change him to frozen, I'm trying to get him established. Then I will change from live to frozen. When is the best time to go up a size, or should I got to 2 times a week with smaller food?
