Can i put this little bottle in my aquarium? Answered

I'm asking this because on the bottle there is a sticker, i dont know if it's harmfull for my fish (in a cold-water aquarium). I want this bottle in my aquarium for decoration, I'm going to fill it with red fluid (foodcouloring i think). Unless the sticker will do harm to my fish. Does anybody know?


The lable will come off if you leave it in water for a while.

There are fish friendly sealants out there. You'll want to coat the bottle in it before using it in the tank.
