Amano shrimp – deals with algae in your tank
Obviously, you must have both males and females to breed Amano-shrimp. While there is a definite difference in size males are much smaller and body shape females have broader tails , there is a much easier way of telling the sexes apart: Females have elongate spots, more a broken line than individual spots really, while males have round spots. Once you have determined you have males and females, you just have to make sure the animals are well-fed, and wait. Copulation normally takes place late in the evening, with the male first swimming around, then landing on top of, the female. If she does not fight him off, he then climb in under her, belly to belly, to deposit the sperm.
