Dwarf platy with injured dorsal fin

[gwand]

This red coral dwarf platy has a chewed up dorsal fin and a white patch on his right flank posterior to the gill. Do you think this is the result of injury or some kind of infection? Thanks.

I forgot to post pictures. Now they’re up. There is a male sailfin Molly, a pair of apistogramma cacatuoides, 6 endlers and 4 other dwarf platy.

You could probably fit the wound size to the mouth of someone in there.

If it’s a bite the scoundrel was Probably the male a. cacatuoides.
