Would a plastic bottle be toxic in reef?

[marcingo]

Just wondering if anyone knows if a small pop bottle would be toxic in a reef tank if it were there for 1-4 days? I have a fish I need to catch so I was thinking of using the bottle trap method since all the other fish other than the one in question are too big to fit in the bottle I think this might work. However I am worried as to whether putting a bottle in the reef tank could poison something. Any ideas?
