Always thought guppies peaceful fish, but I do not like that. Maybe the aquarium too small for them, maybe the case, but I fish quite aggressive. And females. The males at each other people do not pay attention, just do not see each other, but females are often satisfied with the fights. Swim near each other and pinching in the abdomen, and distract them from the way food cannot. Fry for a long time, then ate, my son and I were looking for them in the aquarium, but to no avail. Will appear through the day. In recent years, however, there were even stained.
Even guppies will prey on shrimp. Again, hunt the females. How many shrimp are now in the aquarium - I don't know fish they are not afraid, can even try to steal the Joker from under the nose of the fish, though not very successfully. Hunting is lightning, then the poor shrimp just eats her relatives, after guppy will lose interest in it. In General, even in the aquarium life is a struggle.
Fish to catch in the lens of the smartphone normally not, unfortunately.
