Oh I will play this game. Here are two of favorites from long ago, at a time in my life when reefing REALLY took a back seat and my tank looked like hell. (3/4 of the way through grad school.)
For reference, the pbt is five inches and the clam is...large.
Luckily neither of these animals died. I bought them in 2009 and I gave them to Dong in 2018. The pbt apparently continued to be one mean SOB, even in a huge tank!
So they are not dead, but they are gone. Some of my favorites. I moved them from Somerville to North Carolina and back up to Swampscott before we parted ways.
