Long Finned Zebra Danio Injury

[SarayParay]

I woke up this morning and saw my Zebra Danio is very injured. I want to quarantine it but will it die either way because it will be by itself and not with the rest of the Danios?

It won't die from being alone. However you may not need to quarantine it. I personally would put some maracyn in the main tank and observe, to see if it heals up. It can often happen that when yous ee one fish with symptoms, others hare a problem as well but aren't presenting yet. This looks like the start of a bacterial infection from the one picture, but would be something else with more pictures/symptoms.

Okay, thank you very much. I’ll do that. Is it okay to add the medication if I also have Mickey Mouse Platies and fry? I also have 3 Nerite snails and a pond snail. 
 

The tail is almost gone now. 😞 I feel bad.

Yes, you want to treat the whole tank to keep it from spreading.
