Identification of cause of dead fish

[subramn]

yesterday night when i fed the fish they were fine and today morning I noticed they were dead. not sure what could be the cause but i noticed their tail fins were torn apart. is it something some other fish could have attacked them.

I have guppies and tetras in the tank for lack of sufficient food or may be aggressive fish, i am trying to figure out

i have the following in the community tank

Guppies

Neon Tetra
Black Neon
Orange Von
Ember
Silver tip

any suggestions or recommendations to identify the cause

what are your water parameters? What fish died? It doesn't seem like it would be an "attack" because their all very peacful fish.
