Deceased fish, bruising?

[dmaccy]

Hi everyone

Had a deceased fish this morning. Upon looking i noticed it had wounds / bruises on its body. Does this look like wounds to others? Is this likely to have been done by another fish? Or is this something else?

My guess would be no, looks more like an infection or something... Hopefully someone will come along and shed some incite

Hello
Looks like a kind of an ulcer on the 2nd pic.
You really shoult check water ammonia nitraite nitrate.
Anyway do a big water change.
