Loosing Clownfish

[Greybeard]

So... 140g system, healthy reef, 2x large rainbow bubble anemones (split from a single). Tank is bare bottom, very limited rockwork, very 'open' system. It'd be real tough to hide for long in this tank.

There's a fair sized (10" long or so) Elegance coral at the foot of the island where my nems live. Aside from that, I don't have any aggressive fish eating corals.

Had a pair of chocolate ORA Ocellaris clown for over a year. Seemed to be doing well, living in and around my RBTA's. One disappeared, never to be found. A few weeks ago, I picked up a very small juvenile chocolate Ocellaris to replace the one that disappeared. He seemed to be doing well, living peacefully with the older clown in the RBTA.

Tonight, while feeding, I noticed that NEITHER of my clowns came out to eat. A fairly extensive search turned up nothing... they're gone. No sign of them.

I do have a Porcelain Anemone crab, maybe an inch and a half across, living in the same group of two RBTA's... anyone ever heard of an aggressive porcelain crab?

Fishes? Juvenile Scopes tang, Juvenile Tomini tang, Juvenile Spotbreast Angelfish, Juvenile Lamark's Angelfish, 2x Five Line Cardinals, 3x Pajama Cardinals, Ochre striped Cardinal, Midas Blenny. There's an orange tile starfish... I don't do hermits, so there are no other crabs in the tank... a handful of snails, a few cleaner shrimp, that's about it.

Can't think of anything that would be killing clownfish, except perhaps the elegance coral.

Thoughts?

Oh... recent photos:

Did you look around the tank and made sure they didnt jump? In My 6 years of reefing I never had fish jump, last month 2 clowns jumped from my 2 tanks.

Gotta say I do love the look of your setup.... like a real reef bommie. No clue on the Clowns unfortunately.

Custom screen top, fits well, there's no way out. Overflows are H2Overflows, also well screened. I did flashlight my sump, they're just gone.

Thanks

I'm quite happy with how it turned out.

Got it. I have seen nems eat small dead fish before as long as it fits in their mouths. Just another thought for disappearance entirely.
