Took the hood apart (see the post before yours). This fish literally vanished.
I'm a bit more "broken up" about it because ALL the possible explinations are long shots. It made sense that my Red Scooter Blenny male could "disappear" without a body showing up in the uncovered tank (jump, get eaten by cat or dog, makes sense). But considering that I've never had a fish jump out of a hooded Nanocube unless I was standing there with the lid open (Mama did this once when she got overeager about feeding). Well, actually, I have to take that back. Here's a rundown of my losses in 2006/2007.
Firefish (1 of the pair) - Jumped in uncovered tank, found dead on top of prefilter sponge.
Red Scooter Blenny Male - Vanished - presumed jumped and eaten before I found it.
Mandarin Male - jumped in uncovered tank, found him.
Jawfish (1 of pair) - jumped, found on top of prefilter sponge.
Jawfish (our original "Pearl") - vanished without a trace
A few baby percs in the 6 - vanished without a trace
Red Scooter Blenny - murded by wrasse
Flame Angel Female - DOA with no reasonable explination other than murder by the mate or the wrasse or just sudden death (i.e. heart attack).
Saddle Clown - broke down with disease, never settled in all that well.
Neon Goby (1 in a pair) - got ICH from Day 1 and never shook it.
Margaritophorus female - died egg bound
What's amazing to me in this list is that there's very little loss in the way of disease - 2 to be specific. More than anything, "Vanished without trace" seems to actually be my number one cause of fish loss! Granted, to some extent it makes sense with the baby percs..there's tons of hazards in that little 6 including a surface skimmer, jumping and not getting noticed in time in the back filter chamber, or any number of predatory corals (blastomussa, mushrooms / ricordeas, tubastreas, fungia etc...).
Taking out the baby clowns, it still seems that jumping or "disappearing without a trace" is by far the way I lose the majority of fish. I realize with my open top MH settup it's a risk, and I've accepted it. But closed tanks and I still have 1 I KNOW jumped (the pearly jawfish mate) and had the bad luck of landing on the prefilter, the ONLY place in the tank not wet, and wierder still is the Firefish that did the same thing (even without a hood).
Anyway, that's that I suppose. I guess I'm just on the hunt for a new mate - I *could* steal the halfblack male, but being a misbar and a later color-upper, from my personal experience that's not the best fish to use as "quality" broodstock. Not knockin' the halfblacks, had they actually been true "halfblacks" they were definitely fish to breed with (being the only halfblacks), but I think even JL would agree that they weren't top-quality fish (in fact, when I first asked him about them he quite frankly referred to them as culls, which he doesn't put down, hence he still had them).
FWIW,
Matt
