I was changing the light above the tank..I had the connector hanging on the side of the actual tank. Anyway I saw something fly off the connector and don't know where it went. don't think it went into the tank just don't know.. But it could've been plastic or copper wire or whatever.. but my question is if it was a piece of copper wire or corrosion from copper wire or studs, how much would be poisonous to the tank? Sorry if this is worded funny.. just didn't know how to ask it..
