I've known of an Amano live for 7+ years plus deffo. I took him from a mate that was selling up after 4 years, I had him for another 2 years, same mate took him back after re-starting his set-up. 2 weeks ago same shrimp [Wally] died from climbing out of tank with overhead luminare........RIP Wally. We could never find you [hence named where's Wally] but you'll be missed. A true Marine of the Shrimp world!
