Pennies in water bowl

[Neal]

Copper is highly toxic to all invertebrates and most bacteria and a penny in the water would dissolve a small amount. However long term drinking of copper tainted water can cause copper poisoning in all animals.

There's a company that makes copper plated water bowls, so I'm pretty sure that this isn't the case. Now for inverts I can't speak. You do know that water goes through copper pipes right?

The breeder that I spoke with has been doing this for years with his snakes and all are completely healthy.
