From a German monthly devoted to aquaria, we quote the following: "But now, dear readers, we come to a fish which shows an exceptionally peculiar and touching care for its young--the mouth-brooder, _Haplochromis Strigigena_ (formerly _Paratilapia Multicolor_). This fish is so much concerned about the safety of its young, that it knows no better and no more secure place than its own mouth in which to preserve them. In no other division of the animal kingdom can we find such an interesting example of fostering care for the young as we find in this species of fish. Immediately after emitting the spawn the female again gathers up the eggs and packs them away in her mouth like herring in a barrel. She naturally must employ the organs of the throat and also the organs between the gills and thus the appearance of the animal is greatly changed even to the extent that it looks very much like as if she had a craw. Furthermore, during ths [tr. note: sic] entire period, which is about fourteen days, the little animal cannot take food and is hampered very much in her movements. Therefore in case of imminent danger it becomes necessary for her to cast out the entire brood which then wretchedly perish, and for this reason it is to be recommended to disturb or disquiet these animals during this period as little as possible. Even after the young leave the mother of their own accord, they always flee to her protecting mouth, and thus they present an exciting aspect, when they are first seen peacefully and contentedly playing about the mother fish, until a shadow or a sudden thrust warns them of danger and quick as lightning they dart into her mouth.
