Tang Eating Patterns on Glass

[DarkReefer]

Hi All,

It's been the best part of a week since I last cleaned my glass and today my gf noticed an interesting pattern across it.
Initially we thought it was a snail, but there's no trail line so definitely not that.

I suspect it's my 2 spot Bristletooth Tang that's doing it. Interestingly though it seems to do it as a recurring pattern in the arch every time.
Thought I'd share as it was certainly a little different and surprising to see such a regular eating pattern.

If someone think it's something else, please let me know!

Classic snail pattern. Watch one eat and you'll see it go back and forth like that.

Looks specifically like the pattern left by a turbo snail.

Oh really?
I thought it might be the tang due to the side of what looks like the lips/mouth hitting the glass.

Didn't think it would be a snail as there's no trail behind it, do SW snails not leave some sort of line/trail on the glass showing where it's been then?

If it was from the tang you would see the upper and lower lip marks like it’s kissing the glass

But the markings do appear to have an upper and lower marks to them.

Tang is kiss kiss kiss kiss
snail is back and forth, back and forth

You won’t see a trail from a snail only clean markings on the gkass

None of my snails leave trails on my glass
