Poly #7 Teugelsi came today! About 3", seller said it was WC but it looks more like the cb examples you guys have shown me, though I'm far from an expert with the ID's. I also tried a new substrate in its quarantine tank. It's a mix of black diamond blasting sand and Quikrete all-purpose sand, about 10-1 ratio respectively. The pic doesn't quite capture it, but so far this is my favorite substrate look so I think I'm going to be trying this out in the 100 gal that will soon house my little poly army
