Quick, Darting "Twitching" Behavior with my Goldies...Any Ideas?
I'm thinking this could be a bad case of severe stress, but over the last day or so, my fancy goldies have developed a sudden quick-darting, unnatural behavior in the tank where they'll fly real quick around the water and eventually hide behind ornaments and plants, and their eyes look full of terror, if that's possible -- this happened out of the blue, without me adding any chemicals or changing their diets, so I don't know what could have caused the extreme stress. We did have horrible thunderstorms over the last couple of days, so I was wondering if it could be the loud crashes of thunder which shook our house -- is this remotely possible?
I added some Prime thinking it had stress coat in it, but it's only got slime coat; does anyone recommend getting some stress coat chemicals? What could cause this sudden "darting" and hiding behavior?
