I have a Betta and I recently checked it for velvet with a flashlight. It had what looked like velvet to me but it was in very uniform straight lines and only one certain scales. So I started treatment for velvet and I have been treating probably for 2 weeks by now. Just 5 minutes ago I checked him again but this time with a different flashlight. There was no evidence of velvet whatsoever. So I checked with the original flashlight I used and of course there was the gold on his scales. I compared the flashlights and realized that the one I had been using had a sort of a yellowish lens over it. Since the velvet seemed super exact and only on certain scales in straight lines, could it have just been from the weird flashlight? Should I stop or keep doing meds just in case?
