well thats what i thought, maybe up to 8, but i dont want to crowd them in there, all the other fish all stay mid to top levels, so they wont be sharing their space with any other bottom dwellers. il just start adding them into the tank from the nursery tank gradually when they are big enough not to be snacks for the parent fish. i now have no idea how many babies i have as i added some gravel to the tank, and they have all blended in with the gravel, kinda wish i hadnt but hey ho its a bit late now, and im sure they are happier now they can hide.
