Ok, let me clarify. I ONLY need this to protect the fry when she drops them. Afterward, they will be removed and isolated in a 10 gallon quarantine tank anyway. Maybe all I do need is the simple box for that.
As for catching all the fry, thats not something I really want to do. My current tank doesn't have a lot of hiding space and has 3 swords in it. Most likely she will drop them right after I leave for work knowing my luck and they will be eaten by the time I get back.
Also, how do I know WHEN to move her to a breeding chamber? I bought her already pregnant and shes getting bigger rather rapidly.
