I bought a 3 ghost shrimp to keep w/ my bettas at work. I added 2 to the lone betta and 1 to the betta w/ small fish friends. The next morning 2 of the shrimp were dead and the next day (today) the remaining shrimp was dead. From the reading I did, they are supposed to like low temps (upper 60s, low 70s) and they are supposed to be scavengers as well as algae eaters. I tossed a crumb of algae wafer in each tank and never saw any shrimp go near it. I realize these guys are meant to be food for larger fish, so they probably don't have an incredible life expectancy, but 2 days?! Is there something special I should know about them? Or did I just get a bum batch of shrimp? I'm thinking of trying the shrimp from a different lfs to give them a shot. They're only 5/$1.25, so if only 2 make, I won't be too heart-broken.
