There seems to be some confusion over this, so I was wondering what sizes the rest of you are seeing with your teugelsis. I'll start: purchased mine last April at 7"... now about 14".
Good to know. My teugelsi is by far my favorite fish-- not only looks really cool, but extremely active, especially for a bichir. My ornate, which also looks really cool, has been known to go for days without any apparent movement whatsoever.
