Not the first runt and definitely not the smallest, I remember a normal male that hatched out and I swear a hatchling cali king could have eaten him plus a pinkie. We put him on rat pinkies until he hit ~25g, then fuzzies, on pups I believe at 40g...all feedings were every five days, as a personal rule I do not feeding anymore frequent than 5 days due to liver concerns, some have had success though. The little guy ended up staying with us at the store, he ended up siring at least one clutch, and was ~30 inches when someone finally bought him I believe. The body is more likely to start putting on fat when the animal has a good solid meal, so whatever you feed there needs to be a good lump in him.
