Tenuis or millie ?

[went broke reefing]

Not very good at spotting the difference between a millie and a tenuis. I'm lean toward thinking the one on the right is a tenuis ? Am I correct ?

No expert here, but milli's have tighter packed corallites. Both look like tenuis.

Both look like Tenuis to me.

Definitely not millis.

Both are Tenuis
