When I was breeding frontosas, I never stripped them. The young females swallowed or spit their first 10 spawns. Eventually they held to term. If you are going to strip them, make sure you have a large egg tumbler. The eggs are huge.
We don't use a tumbler We use a strainer and have a stream of bubbles come up from the bottom. This system has served us very well we tumbled front eggs in it for a friend withgood success. We would love to let her hold to term but don't want to risk loosing a batch or more until she will.
