Aggression?

[Arkham]

After having my frog for a while now, I've come to realise how silly my first question was 😂
He has grown an awful lot and now eats around 4 small pinkies every other day, with locusts and worms in between.

I'm assuming that he's a male because he croaks at night?

Anyway, lately he's gotten quite 'aggressive' towards me.
Well, he launches at my hands
I have always use feeding tongues when feeding him so I don't know why he'd try to go for my hands /:

Is there anything else I can do so he wouldn't associate my hands with food?
Or is he just being mean? 😂

It's not too much of a problem, more of an annoyance.
Especially when poop picking and moving stuff in the tank.
Being bitten by him hurts 😢
