Its like a little white on the bottom lip and sometimes when she opens her mouth, a whitish strand would come out(its attached with the whitish stuff on lip) and she would suck it back into her mouth... like she's playing with it...
It might be the first one. When will the other fish get it? I want to make sure and wait to see if the fish that has it will stop eating or become sluggish. He has had this white stuff for a couple of days now.
Im not using any right now, as i am still unsure about the if she has it. The pop in, pop out of mouth thing is gone and it looks like the whitish/clearish stuff is clearing up. I'll give updates later on or maybe tommorow.
