So I think I killed our fish & yes I did cry. I cleaned his tank the day before his passing and the next morning he was gone. Angus has been apart of our family for 4 years ( a gift to Makayla when she was 2.) Long story short...never use backing soda to clean a fish tank...even if you rinse it really, really well...It's a KILLER. Actually I guess that makes me a KILLER... My Bad! Sorry Angus! Thanks for being a peaceful image of grace for our family to enjoy. You will be missed, our fishy friend.
