Awwww, that's too bad. Starting a fresh tank is tough to say the
least

If I had it to do over again and I started a new tank. I'd buy nothing
but Zebra Danios. They're cheap and the little suckers can live through
just about anything. Once they get the water all "fishy", slowly stock
what you want in there.

Don't give up. Once the tank is established, it's worth the effort.
