2 of my male and 1 female guppies are just sitting on the bottom of my tank, not interested in food. any ideas??

p.s all other fish (guppies) are ok.

tired/ stressed? i was goin to say bad water conditions, as they sit at the bottom when this is so, but u say all ur others are fine so im not sure... a more experienced answer would be better..
