Fin Rot or Tail Biting?

[Miakemi]

The lighting in this picture isn't very good for the colors, but I was hoping this would be enough. Link has always been a bit of a tail biter, but recently it looks like it's gotten a lot worse. I just need to know if I should still treat this as tail biting or if I should treat it as tail rot. Thank you.

Does Link have red coloring naturally? Maybe you can describe his coloring for me, that would help.

[Miakemi]

No, it's usually more of a blue-green coloring. He's the fish in my avatar if it helps. I read that fin rot usually had black or red, so I wanted to check to be sure before I use any medication.

For either fin rot or tail biting you can use 1 tsp/gal of aquarium salt to fight infection and promote healing. Use this dose for 5 days and if there's no improvement or it's not gone, up the dose to 2 tsp/gal for another 5 days before you consider medicating.

Using medications for everything lets bacteria build up a resistance and makes the medication less effective.

[Miakemi]

All right. I'll try that. Is it safe to say that this is fin rot, then?

that is not tail bitting though it is between tail rot or body and fin rot

If he doesn't normally have red in his coloring and from what you said, he doesn't, then I'd say it's fin rot. It's best to QT for the salt treatment, it makes the 100% daily water changes easier. Put him in a small bowl or 1 gallon tank if you have it.
