This is my male, red VT, Leonidas. I got him April 15 and his behavior hasn't changed at all (he eats normally, likes swimming around his plants and decorations, likes his heater) but I noticed some rather concerning spot/patches on his face near his gills. They are larger on the right side of his face than his left and are a shiny gray/brown/silver metallic color depending on the light. (I scooped him out of his tank to get a quick picture if anyone was wondering why he happened to be in a small container)
