Hello. I have a few yellow labs that appear to be turning white from tail up. Not fuzz or ick. The water parameters are 0 and 0 and 10 or so and do 40% wc 2x a week. Temp is 78-80 and ph naturally high in city water. I can't find any info. I think she's being harassed a bit by the dominant male but I assumed breeding and mating. She wasn't this color 2 weeks ago. I'll attach pic the bright yellow one isn't her but same color they were for reference.View attachment 1299202 View attachment 1299203 View attachment 1299204 View attachment 1299205 View attachment 1299206 View attachment 1299202 View attachment 1299202
