Thanks, when I take in an animal I try to do it right. I guess mistakes are made, sometimes with tragic results. I am glad I bought the master test kit, it's comforting to know that you have the correct water parameters. I hope that no other fish are affected; I'd hate to see them go out like that.
She was the crown jewel of the sorority; there is a big old hole in the tank now.
Bettas are seen by too many as throw-away pets, I see it all the time. And that is a shame. There is a HUGE personality in those little colorful fish.
I try not to rescue fish from places like Walmart, because I know that another will just be ordered to take its place.
Again, thanks for your help!
