Nice... 8)
.... sigh ..... I wish my tank could look like that.
(I guess it would, if only the frags were mother colonies, the front glass wasn't scratched to the point it's smokey, ignore the flatworms, and pretend there isn't a brown snotty goo covering everything and clogging the overflows. Yeah. Other than all that ..... my tank is completely identical. Well, minus the colours, and nice shapes, and non-necrotic caps of course. But other than that ...)
.... Seriously, very nice. I espescially like the lavender cap in the left back corner. I have a piece like that, that I rescued out of a bargain bin at a LFS, but it has so much recession it is a chore to keep the algae at bay. It hasn't receded in my tank, but it hasn't recovered yet either (wild collected specimen so who knows how long this can tank).
Neat idea having that other cap "surrounding" a powerhead intake. I bet you will get some wild growth on that guy.
cheers (I really am jealous, one day maybe I can hope to have half as nice a tank as that!!!!)
