i saw that petsmart drop a single hex bolt into a tank
what is that for? something to do with the metallic properties of the hex bolt?
also saw they added one of those large goldfishes with the bulbous heads (not the ones with the bulbous eyes). I suppose those are for keeping the tank "clean"?
They placed one in almost every tank....but went there a couple of days later and saw one of them floating dead and thought it was kinda poor fish care to leave him floating for the customers to see but at the same time though it was kinda funny that the big one died whereas the other fish in that same tank survived.
