For sure if the little guy is only 50 grams. A 6 quart is all he needs. I keep mine in a 6 quart until they hit 300 grams. He needs that security. He can easily go 5 or 6 weeks without eating with no ill effects. So don't panic.

Hoppers are a bit small for a baby ball, but if that's what you have it will work for a while.
