Not at all. No damage to the snout. Every reason to believe it's a latent or obvious illness that lasts a while, a week or a few, or an end-of-life withering and then death.Dam that was a nice bass. Sorry for the loss.
You think they are getting spooked and running into the sides of the tank?.
All the external redness, swelling, and physical damage are from the final stages of dying and post-mortem feeding attempts by opportunistic tank mates. They have nothing to do with the primary cause of death (largely unknown to me) for any of these pbass.... They look like the got beat on pretty bad at the end there.
