For now there are no clownfish in there. I did have a pair living in it at one time (they live in a carpet in a different tank now). The effect was exactly the same as what you see here (ie., you find yourself asking, "are there clownfish in there?"). Clownfish are .. well, I think they are somewhat dumb and uninteresting fish on the whole. They just hid in the anemone so well that you never saw them.
It's the same story with them in the carpet. When the carpet was smaller, you'd see them. E.g.,
That was two years ago when the carpet was about 6". Now that it's more like 15", this is about as lucky as I can get to see the fish (this shot required a lot of patience, as the female will only peek out for about a half-second. The shutter lag on the camera in itself was enough for me to miss most of my attempts to capture her on camera):
The male is even worse, he barely even comes out for food. It's kind of too bad, they're really cute fish, but you just never see them.
My long-range plans for the ritteri however are to try a pair or a trio of skunk clowns. They seem to be a bit bolder in personality and more out in the open as compared to ocellaris. Failing that, maybe some onyx or black perculas and hope that perculas or at least whatever ones I find will hopefully be a little less shy.
For flow the sump return is a Rio32HF and then there are also two Maxijet upgrades on there (makes them like mini-Seios or mini-Tunzes - best $20 you'll ever spend if you have Maxijets kicking around).
