Yikes! I'll have to watch for that. Were they overdosing it by chance? That's the only time I've noticed any problems (when I overdosed) and that was on a feeder/pond goldfish that was so far gone I thought it was just his time. Now I'm wondering...
Thanks for the effort, Anne!
If you'll let me know which forum, I'll look for it on my own ~ don't want you to have to go that far out of your way. Thanks for the info so far, though!
