I have 4 MMP and a betta. The Betta is old though and he won't be around much longer. So you think like 1-2 weeks?Until they are big enough not to get eaten . Depends on what other fish you have in with them . I only keep Platies so it doesn't take long till the adults can't eat the babies . Helps if you have a lot of plants for the little ones to hide in...lol
That does make sense. I've never had a fish that give live birth so this is all new to me.I would probably change a gallon or so a day if you don't have a filter . If I were you I would get a breeder box so you can keep the babies in your main tank with filtration . Hope that makes sense .
