Acro Frag Not Extending Polyps?

[GMGQ]

Yeah, actually I have. It's pretty much the same, 24/7. Plus it's polyps were extended at the LFS like the rest of their acro frags, while the lights were on. Plus their MH's are only about a foot above the frags, so they're pretty close. But I couldnt recreate it even when I put it at the top of my LR...
