Goldfish are food. My 7" Albino Palmas has killed several that were far too large for him to eat. He just bites their faces and kills them.
Yours might not be big enough to eat them yet, but that won't stop them from trying, because goldfish are like sheep.

I'm pretty sure if you're gonna set goals for fins not eaten a good number to aim for would be zero but maybe that's just me...
