@ Indy, were pretty sure its just a pigment discolour no nothing to say other wise.
@bettasrule, i have a girl who started white turned gold then yello and faded a little then developed black patches lol
@leenix, not good. the pineconing worsened while i was at work and she develloped two fluffy white masses on her head, before bed she had some on her side too. shes in dosed water with pimafix and salts as per directed by my fish expert. she may not survive the night but either way shes had clean water and some love.
