Mysterious Death, Confused.

So I bought this big male molly, see pics. Quite active in the tank etc. He just stopped eating sometime back and kept himself confined to a corner at the water surface. Then died the day before. Parameters are all fine, other fish is fine too.
Only one observation, he used to chase probably every female agressively all the time..he suddenly stopped it..not sure why and then died. I'm really not sure whybhe died... any suggestions?

 

How long was he in your tank? How did you acclimate?

 

1.5 months...he was absolutely fine...chasing mating females...thr r some fries as well thru him

How long was he in your tank? How did you acclimate?

 

Do you have any pictures from right before he died? And/or after death?

 

The second pic is few hours before death. I did not take any pics ppst death...but did inspect it..no anchor worm etc etc..his body was fine

Do you have any pictures from right before he died? And/or after death?
