Help! Male Black Guppy Is Sitting At The Bottom Of The Tank!

[guppy!]

so here it is: my male black guppy was ok this morning and when i came home tonight(a few hours later)he was sitting at the bottom of the tank kinda sideways. this is what he has been interacting and doing with:
1)tank mates: researched. is all good.
2)has been with two female pinnapple swords and trying to breed. (no luck )
3)has been with a female guppy and she was prego already so no luck for him there either
4)eats a god amount once every night
5)eats "cobalt tropical flakes"
6)has no other seeable problems
7)has not ever been actiing weird before

I have had him for about 1 month and got him from a petstore. i forgot to ask how old he was
help me!
(also is in the same tank as 3 day old molly fry. they are in a breeder in the tank)
