one of the females is pregnant, and so might the other 2, but i do not know whether to add them to my mbuna tank (contains 2 socolofi, 3 yellow labs, 2 mollies, 1 JD) or do i add them to my oscar tank (1 small albino oscar)? i want them to have fry, but at the same time, i want them to survive also. so which tank will they have the most likely chance to survive in? (the mbuna tank has a rock cave, a copper domed castle, and lots of plants)
