I have a small peacock bass and arowana in a tank who are very aggressive feeders. While feeding, I dropped a piece of tilapia with a pellet inside right in front of the bass. The arowana, on the other side of the tank at the time, shot over and went for the food the same time the bass did. The arowana got the better of the bass and left a big scrape on the bass’s side. I have done methylene blue dips on the bass and other fish before but was wondering what I should do for this. Should I just leave it alone? Will it heal naturally? Or should I treat him?
