With tango yes, tango was the first one I asked you about, who nested over half his tank his second day. The second one doesn't have a name. I'd have to go check the ventrals, see if they've gotten longer or not.
So today has been a day of hell for me on other fronts. My course I had labs done for, doesn't need labs done and passed in, it's the assignments. But it clearly states that labs are worth 50%
Tango... he's just larger, thicker, and more fins, including vents. The bottom picture is the one in question.
