Well, originally I blamed it on the murderous coral banded shrimp I had. He may have been the main culprit for most of them. I originally had one pair. After about 3 months, one died. About 2 months later they came available at the LFS again, so I got 3, (cause one of the guys said he'd sell them for $12 each or $25 for all 3.). They seemed to acclimate fine, were doing fine for a day or two then they all disappeared. About this time I found my CBS attacking one of my cleaner shimp. I moved the cleaner to a separate tank, where it lived without eyes for another 5 months or so. I didn't try SS again until after the move, (I got rid of the CBS.) I still had that one surviving SS, and so when the LFS got them in again I bought 3. One went in my work tank, (It's doing fine.), and the other 2 went in the main tank. They both seemed to be fine a couple hours after acclimation, but I never saw them again after the lights went off that night. My one lonely one is doing fine. I don't have any fish that are known shrimp eaters. The SS have kept me from getting a hawkfish for years now. If one of the clowns was harrassing them to death or the pygmy angels had developed a taste for them, or something bizarre, I'd think that the single one I've still got would have become toast by now. The only thing I can think of is that the one sexy shrimp is killing them off, or has somehow figured out how to evade what has gotten the rest of them. I've put other shrimp, (cleaner and peppermint) in the tank and they're doing fine, so I don't think it's something that the older SS is acclimated to that the newer ones aren't. I've just chalked it up to one of those pecularities to 'my' tank and not put anymore in there. I'll probably try another one in my nano at work, maybe one in my wife's nano when she gets her algae issues sorted out, but I'm not trying anymore in the main one until the existing one checks out.Sugar Magnolia said:
