Well, We have here a clear and well-documented case of a syndrom called- FDAP (Frustration due to Absense of Procreation). Your boy, not having succeeded in breeding his fishes, is simply frustrated, and is trying every little help he can conceive, to bring about what he perceives to be some sort of assistance to the process of procreation of hus fishes (see New England Journal of Psychiatry, Vol. IV, pp. 345-257, 1993). Incidentally, there could be another reason. It is a well known phenomena that human semen can reduce the chemical ph of water, thus making the aquqria water more suitable for the habitat of some rare tropical fish (see "Piranha", for example). Thus effect is greatly enhanced if the Male organ and the testices in their entirety are carefully removed from the child's body and immersed in the water until decay or until consumed by the fish. All-in-all, there should be some concern on your part' regarding the overall emotional well-being of both yourself and of boy. Take care!
