About six weeks ago I bought a Randalls Shrimp Goby along with it's symbiont; a little yellow Pistol Shrimp, they built a burrow & behaved naturally but after a couple of weeks the Shrimps claws seemed to just fall off and it disappeared. I think it may have had a little trouble molting.
So after a couple of weeks when clearly this Shrimp had bit the dust I invested in another, a gorgeous red & white stripy one hoping it would keep the Goby company, but what has happened is the shrimp has found a cave about midway up and behind the rock work and can only be seen with great difficulty. Whereas the Goby perches at the bottom in front of the rockwork waiting for food!
I though Pistol Shrimps were obligatory burrowers so why will this one not get stuck into the sand and rubble like the previous, is it a matter of patience here or have I got a rogue one that prefers to live higher up in the rockwork!
Any suggestions? I have a 24G (US) tank with various coral, Common Clown and a Randall's Goby which is meant to team up with the Shrimp!
