I saw that at a pet store near by they had a piece of lemon in the goldfish tank.. can i feed my gold lemon?? is it good for them??

I wouldn't in my opinion. It could change the ph of your water as the lemon is acidic.

you know what i was thinking the same thing.. but yeh i guess im not going to then.. thanks for your help barbra..

Yuck, can't imagine a fish liking a lemon! Then again they do like spinach and all that yucky stuff...
