I have infant formosa I can try and catch for you if you want a couple.
Killies, in my experience, DECIMATE shrimp.
One time I brought home 6 from Scales (Thanks Ghanzafar! ), and went to put them in a guppy tank.
I completely forgot I was housing a young killie female in there, who now lives at Viktor's... anyhow, she about smacked her lips and went to town.
I never, ever saw her move that fast before or after. She ate 4 of them in under 2 minutes, and was so full her belly looked like a Ram's for two days afterwards, all glowy red.
