Biology a question

[rossb]

To begin with I am not having any tank problems and no fish are exhibiting any problems, this is just a question. I know this is a bit morbid, but I was wondering what type of a post mortem you do on your dead things. Do you try to figure the cause of death?

Also I think I have an evil critter in my tank that is attacking my shrimp and crabs. I suspect something like a Mantis. This morning my SLF crab, that was ½ through a molt, was the latest victim. I have been placing Bob’s mantis trap out without any luck. Where do these things like to hide? Any tips that could help me narrow down the search area?

Thanks…ross
