I woke up this morning to my Denison barb looking like this. I did a cleaning the night before.

Looks like a predator is in the prawl in your tank. What are the tankmates?

Ok, more than one known species of territorial or fin-nipping fish. That fish either got into somebody's territory or showed weekness that another fish used.

Any suggestions on how to heal him?

For injuries like this there is just frequent big volume water changes. Maybe some indian almond leaves. Will take at least a month to grow halfway back. With those tankmates I'd sadly expect the fish to be beaten up more in the near future.

I have never had issues with aggression in the tank before. Always swimming around each other but never marks like this. I will continue to monitor the situation. Would it be any benefit to increase water temp?

No, why should it? Except increasing bacteria activity nothing would happen.

That can suddenly happen. Usually in such a case the fish shows some kind of weakness we as humans might not notice. Other fish usually abuse such weaknesses and go for a bite.

I know it is helpful in killing ich. Thought it could be a useful prevention to ick

Have you had ich in the tank recently? Do you expect the fish to get it somehow?

No just trying to prevent something like that from happening

Don't worry, in case of injuries fungi and bacteria infections are the likelier thing to happen and for those you should keep the temperature at about 24°C to prevent too quick development. The waterchanges prevent a lot of these secondary problems as well.
