We have gold barbs, torpedo, green barbs and tiger barbs. Just noticed that all the green barbs and tiger barbs are swimming erratically, nose down and slightly sideways. Stuff coming out their mouth in a white cloud. Bloated stomach. Have attached a video. Went to test the water, all fine and the guys there said they've never seen this before. All the other fish are fine. One tiger barb upside down but he's not been great for a week or so pretty sure that's unrelated. Thought it was possibly a breeding thing but wouldn't be from their mouth? Also thought stomach parasite but odd how it's only the green and tigers affected?
