Well, I guess if you are concerned with them getting eaten, then you could throw in a full plastic plant. That would give them some hiding places.
Or, if you have a large net, you could scoop them up and put them in that as it lays in the tank.
Or, you could keep the other fish well fed and place the plant in the tank.
Or, you could try to put them in a cup until you get a breeders net. But I wouldn't leave them in there very long.
How many babies did you have?
