Breaking a possible bad habit?

[MixWizard]

My 8 'Scovies are almost 5 weeks old and since introducing them to fun snacks such as peas, they nibble at my fingers while I'm changing their water, food, etc. Well that nibbling is getting more aggressive, nothing painful but I'm curious if this will get worse as they get older.

Any suggestions as to correct this behavior or is this just a stage they go through?

Thanks!

My mallards did that as well, but I just tapped their beak and said no and eventually they understood. They are 3 months now and no more nibbling! ( except for my toes in the morning when they want breakfast)
