Question about a Space Invader

[WhatCouldGoWrong71]

Space Invader - The bluish picture was taken 3 months ago, I have been waging war on GHA and while I am attacking the cause of the problem, I also scrub my rocks regularly, thus I changed my scape about 3 months ago and relocated the Space Invader. I know the placement shouldn't be an issue, many people have it on the substrate. But I know the move could have caused it to stress to perhaps. My question is, if you look at the blue picture and then look at the other two, it looks a little thinner and the tips are a little darker. Could the darkish tips be growth? Does it look healthy to you?
