Help! Is my lysmata gone again? I got two, then added two later. In the first two one died and I found it's dead body. In the second two, the same happened and I thought both were dead until the smaller emerged from the LR. Now the two surviving are gone!?!?! Either they are hiding so well or they were eaten/dead?!?!? frustrating....before it was a CBS killing them and at least I know/saw it done. At least a CBS is very hardy and cheap (lysmata cleaners here cost 4x a CBS).
