One of my neons has a spot on the tip of their tailfin and one has a white spot about halfway on the red part of their body plus a smaller spot on the tailfin as well.
Sorry they are so blurry....they are fast!I Haven't noticed any change in behavior..I did turn the heat up to 86 for a few days and nothing changed so I raised the temp to 88 and it seems to me the spot on the body of the one neon is smaller today, but could be wishful thinking..
Water is 0 amonia, 0 nitrite and <5 nitrate so water is good. Moved them from another tank about three weeks ago, so I am thinking stress if it is Ich...is this what it looks like? I've never had anything before..
