Yeah our tapwater here is one of the best in the world. It has 0 KH coming out of the tap and my wilds thrive in it. Makes it so much easier than having to go through the hassle of using rain or RO water.
I was lucky in that my second cousin's wife has diabetes, and she is trialing a medication that is light sensitive and needed to be kept in what is essentially a film canister. It's funny to think how common film canisters used to be back in the dim, dark ages when all cameras used film.
I get some of my wilds through Xtrembetta. I believe he has burdigala, brownorum, uberis and rutilans, and all of mine from him have been male/female pairs. He is also really nice to deal with, and all of my fish from him have been healthy and of breeding quality.
