They will absolutely die. There's something in the water than can be neutralized (I think) with the water drops. Putting fish into water from the faucet is a big no-no.
Water has many chemicals in it put in by the water company, like softeners, chlorine, teeth cleaners, its best to use Ozark natural spring water, also fish like acidic water, the water you drink out of the fa suet is more of a base than an acid.
they willd die soo fast you cant even put salt water fish in a salt water fish tank until you get the ph levels perfect youll spend a crap load on the fish and theyll die in prob the 1st hour. trust me.
