At least it died before the new year. Kind of bums me out, I just did a water change about 5 days ago. Water test comes out ok, other fish appear to be ok. I don't think the death was because of stress or anything like that. The fish that actually died (phantom black tetra) has been acting weird the past couple of weeks and was actually kind of fat, almost pregnant looking. Not sure cause of death. Just kind of bummed.
