Skark (my rescue betta, red/blue VT) and Xyphoid (red VT with long pec fins). My third male Riot (was a black HM) died earlier this week. He somehow figured out how to teleport and killed himself doing it. One of the stranger things I've ever seen with a betta. Got himself past not one, but two dividers, past another male betta, and into the section of the tank furthest away from where he started, without a single scratch or tear on his fins (which you would think would be present if he did somehow manage to wriggle his way past a divider and another male betta), but he was dead. Still haven't figured it out, I've yet to ever have another fish make it through the same type of divider, there was no space at the bottom he could have gotten under (substrate covering the bottom anyhow), the top is flush with the top of the tank edge with the water level being a couple inches under that, and the sides are siliconed in place.
