When I got up today I noticed that his bottom lip looked like it had been scratched, that's why I moved him in with the tsn. He was in with a Senegal bichir, a female Jack dempsey, a gibby pleco and a managuense. All of them are around 3"-4" except the gibby which is about 6" and the dominant one. He was getting along with everyone, they completely ignored him, and he wasn't avoiding anyone (even though he is the smallest in the tank. I just wanted to know if he started something that he couldn't handle.
