anchorpuller.....I've seen people that use food coloring to give minnows an orange/red tint, and it seems to not harm the standard minnows. But....another tribute to the Roseys is their durability, being a fathead minnow they are some tough little guys. I can't answer about how long to leave minnows in the coloring agent, surely it must be deleted with water to sustain their oxygen intake. I'd experiment with one minnow at a time to get a feel of how long to leave them in the mixture to get the color where you like it. Good luck!!Originally Posted by anchorpuller
PS....as an after thought, don't use tap water unless you are on a well. Chlorine is a minnow killer.
