That's very much possible yes, but she's alredy chewing on them, just spitting, so I'll rather wait a bit more than to risk having to move her twice if she doesn't do well with competition yet.
It'd be very hard to feed her worms in the pool, the others would eat most of it, here I can have a control on how much she eats of anything, if I decide to take a break from the starving method.
Perhaps I could have kept the bigger one that ate prawin in there for a little longer, that way she'd be able to "teach" with no need to stress the small one by moving her. Oh well, she seems pretty close alredy to eating prawn, I'll wait a bit more
