Thanks, he's definitely healthy. I got him to take pellets the second day I had him, and he's very active even with the light on. I'm very happy with him.
He's about 4 inches. He's in a 180 gallon with a 6 inch VATF. It's an interesting cohab, as the VATF stays near the middle to top where I have the powerheads flowing and the mala stays towards the bottom where the water isn't moving as much. So far no disputes, and they are a nice size to cohab since neither will fit in the others mouth. Here's a quick pic of the 2, they look way different in size than they are because the wolf is along the back glass of the tank and the VATF is up close to the camera.
