Sick platy

[roydesilva]

So a few days ago I noticed my male Amy sitting on the bottom of the tank... I just thought he was having a rest but he hasn't really come up since then and today he didn't eat. All my other fish are fine and acting them selfs no one is picking on him, I'm worried about the little guy, can anyone tell me what's wrong??

What are your water parameters and what size tank is it? What other types of fish do you have, and how many?

The parameters are perfect, it's a 70 gallon,

I have
2 angel fish (1 6 month old 1 adult)
6 serpae tetras
4 6 cm bala sharks
4 mollies (1 adult male 1 4 month male 2female)
2 large corys
1 pearl gourami
1 three spot gourami
1 dwarf gourami
3 platys (2male 1female)

All the fish get along perfectly and have had no cases of fin nipping I check every day
I'm not sure if I'm over stocked a
Or not the guy and the lfs said were not but I'm not sure so if someone could tell me that aswel tht would be great
