Is there a heater in the tank? What's your parameters? How long have you had the ray?

 

[James Dean]

Parameters good, no heaters in tank. Do two 40 % waterchange a week.Ray been with me for 4 months. Eating well. What does it look like? Def not ich. Patch was only visible last week.

I've never seen these patches on my rays, but I've heard of others getting these mystery patches that come and go with no explanation. I'd just keep doing what your doing and it will probably go away.

Did treatment with salt yesterday and looking better today. Thanks Bigfishnut.

Did they appear immediately after a decent size water change 40% +?

 

[James Dean]

Could be. Got back from work and saw the patch. Patch not spreading. What can i use or do to help? Did another 40 % waterchange yesterday.
