My ghost shrimp gave birth in a breeder tank 3 days ago and I have since moved her back to the main tank. This is my first time owning ghost shrimp. The babies are kinda just floating upside down. They're definitely alive though, because I'll see them darting around occasionally. Is it normal for them to be floating like that? They're just kinda hovering at the bottom head down. Some of them are on the glass, but some are just floating.
