If the NLS ultra red will not colored up, nothing will. It is unlike any quality pellets including other NLS formulation.
If you decided to give it a try, please keep us update on the results. And if you can take a before and after photo to share.
I can definitely give it a try.

My guys are used to the 3mm Xtreme Aquatics pellets, but 2mm should be close enough. They usually totally ignore the 1mm pellets I use for my smaller fish.
