I found this little guy at PetSmart. There were four that I liked the colors of, but when I lined them up and took a closer look 2 half moons had decently damaged fins and weren't as active. This left one double tail and another half moon. The double was pretty enough, but the half moon was feistier. I went with this one because it's colors were more unusual and, like I said, was feistier.
Tonraq's fin rot is already getting better. Instead of black the infected edge is now grey. He's very active and loves swimming around the column of bubbles from his air-stone.
Hannibal is just as active, curious, and demanding for food as always. He doesn't mind the ghost shrimp, Venkman, being in his half of the tank either. I should get another for Tonraq's side and see how he reacts.
