But really, I've heard some people just switch tubs with the females and they do great. I've heard that "washing" off the female isn't as important with egg layers than with live bearers.
I stopped "washing" them down years ago and have never switched up tub slots. They all seem to return to normal and get right back to feeding in a day or two...
