I have Spider's now... but will keep in mind the others if I don't like the coverage. My canopy is going to be about 13", so I'm hoping that with the extra height, I should get decent coverage.
Yep... Gem Tang it is. I'd love to get one, but I already have a Yellow who thinks it's the "King of the Hill". I'm going to stock my 200 with various other species and put the Yellow in last, but since the Gem is a Zebramosa also, I don't want to risk having both.
