Well my clam died after the move, had him for close to 2 years. I can't keep clams for very long, that one was the oldest of several I tried to keep. You need to have a very stable aquarium. I just have to live with the fact I can't have clams. i won't try again, I just don't want to kill anymore clams. Fish are pretty easy to keep, just like fresh but your have to learn how to care for them a little more than fresh.Awesome setups and the fish look great. That's the largest Tridacna Clam I've seen in a home aquarium. Can't wait to see the development of those frags.
