Is Butter toxic to fish in small amounts?

[Zac]

Hey all,

So I fed my fish a deshelled crushed up pea that was left over from last nights dinner. I forgot that there was a little butter put in the peas. 
 

Obviously you shouldn’t feed your fish things with butter. But I’m wondering if it will have any ill effects if it was a minuscule amount? I don’t believe it would be a problem, nor could find anywhere that said it was toxic in small amounts but still…I figured I’d ask. Obviously there’s nothing I can do about it now but just reassurance is good😅

I think you'll be fine, might see a bit of an oil slick on the top of the water possibly.

That’s gonna be the most delicious pea that fish has ever eaten! 😉
