Possible Lateral line Issue

[joeytoe]

Ive noticed on one side on my silver Aro that Part of his Lateral line is a lil discolored. It looks a little dark in color along his Lateral line inbetween his scales (like at the stop an start of each scale).

Ive never seen this before, Any thoughts?

I had this happen with my black for a while. I didn't do anything to treat it, I just kept on top of my water changes and it went away after about a month. I never could figure out what caused it. How are your water levels? I had a nitrate spike right before it happened with my guy.

I did have a problem a week ago, I had a slight bacterial an Algae bloom happening. Waters perfect now though.

Thanks
