Ok I can't figure this out... I see all these people with lil short palys but mine keep reaching up like they need more light... I don't get it though I have a 90gal tank with 2x 250w 20k and 2x150 14k over this tank... sps does fine even at the bottom, in fact I have to find shady areas for shrooms and softies... they spread pretty good I just like the look of the short tiny zoas...
