Really? My tanks make me totally unhappy. Your tanks make you happy? Wow, you're weird.
No seriously, just compared to other nice tanks (and I'm even referring to Canreefers tanks, those who put a little thought/design effort into aquascaping), all it has is splashy colour. Never once did say the colours weren't impressive (I'll give credit where credit is due, and: "wow to that" .. but .. just ..), the overall package isn't.
Guess I've been in the hobby long enough to get a little opinionated as to what makes a nice tank. If a tank looks like a guy just went out and dropped 5k on a whole bunch of Bali aquaculture at once, .. that's going to impress me less than someone who looked at his glass box as a canvas and took a little flair and imagination to the aquascaping.
I should add that I make no claims that I'm some kind of aquascaping genius. I apply the same criticism to my own tanks.
As for the clams.. the thing is, they do like to move around a *little*. So perched on a cliff side odds are good they'll fall off sooner or later. If you look at how clams are in the real reef, they're usually so buried into rockwork that all you see is the mantle extending, and it almost looks like a nudibranch crawling on the rock (until it pulls in if startled).
That's not really practical to replicate in most tanks though. I try to make a sort of "bowl" like impression in the reef for my clams. The two exceptions right now are my squamosa which is too large to fit on the reef and my derasa (which I just didn't have a good spot for). Some clams are found on the bottom but croceas and maximas in particular seem to me are found near the tops of reefs.
Just my $0.02.
Flame on...
