I have a large fire shrimp and it is actually one of the most personality filled shrimps I got. Not to mention it is quite hardy. I keep adding peppermint shrimps but can only seem to keep one at a time. I don't know why but I try to keep three and always the same one is left and the others are gone. I have no predator fish so either another shrimp doesn't like them or they die for another reason and get consumed. As far as the fire shrimp goes you can buy large ones online for around $30. I wouldn't pay $64 that's for sure. Mine will even crawl into my anemone to steal food from it. It eats everything from frozen, freeze-dried, flake, pellet, live brine, etc. I highly recommend them. Also it stays out during the daylight hours too so you can appreciate it's bright colors and unique behavior. I will add another at some point.
