So I just bought a new bottle of Prime, went to check the fishes and noticed a smell. I had just changed the goldfish's water so I attributed it to that, but a quick inspection led me to a different source - it was the Prime I just bought less than a week ago. :/ It smelled vaguely the same as goldfish doo.
I'm pretty sure my other Prime didn't smell like that - I checked the liquid inside, I thought I saw little black things swimming around (TONS of them!) but when I poured it out, nothing. They vanished.
This is unsettling, I've been using the stuff on all my fish and frog tanks doing big water changes this week. :(
AArgh, and the rehab betta with popeye hasn't been improving... I'm having a rough life here. >:l
