I've read about the characteristics on "toothed tongue" as it relates to the Arowana - but can anyone share pictures or have insights on it's growth as the Arowana grows?

I'm curious as my Leichardti get's bigger (about 8", head to tail at the moment), I've noticed the end of the tongue forming with what seems to be large "pink ball-like" shape. I can't get a clear view of it but it looks to be almost too large for it's mouth. Is this common or expected?

Any inputs from those who have experienced who be appreciated.
