i do the same thing. wait about 2 weeks, pull her from the tank and strip her, put her directly back in the tank, tumble eggs til i see them swimming from the top to the bottom of tumbler, then i'll let them free swim (in a seperate tank). it doesnt really have to be two weeks, it could be longer or shorter depending on your schedule and how busy you are. you just want her to hold the eggs long enough to make sure their fertilized and if possible you dont want to wait til shes about to spit because she'll be weak at that point.
