"Stripping a fish" means removing the eggs from a mouth brooding fish. This takes some practice to do well. I usually don't strip until the Frontosa has been holding for at least three weeks. This enables me to put the fry in a breeder basket without "tumbling" them. I like to strip on the floor, so that if I did lose grip of the female Frontosa, she won't fall far. My wife insists on the towel.
