in the window tank

This little shoot that came up against the front glass

looks like it must be off a runner of the crypt moehlmanii- it's got the same pale color and longitudinal veins. But it's so small compared to the size they usually come up as. Not sure why- because further from the light source? a less nutrient patch of substrate? 

Nearby for comparison- thickets of crypt becketti. Which I thought it also could be, but doesn't match.

Note: still have three white cloud fry in here! The biggest one I can now see red on the tail fin, and a bright blue streak horizontal in certain light. I tested the water last week to make sure the spot feedings of first bites wasn't affecting water quality and nope.
