ok, when i get home from work today ill put one up. i've had my tank for about 2 1/2 months now so still working on it. The guy at the pet store mentioned that they were shipped in about two days before i bought them, do you think he could have just been really stressed, and maybe didnt make it due to stress? Are these shrimp hardy? From the research that i did i gathered that they are, but thats not always very reliable.
