I noticed last night that it looks for all the world like Fritz had a bit a bleach dropped on him. his scales are fine, no Fuzziness, and he ate well this morning, but he has a bleached out spot that wasn't there two days ago. I checked his fins for rot, but no.
Any ideas as to what is going on!?!
His blue has shifted from Dark blue to light green randomly before but I just asumed it was the light. is this a marbling or do I need to order some medication?
