Gig'em!
After work today I went to my LFS for RODI, and I made the mistake of browsing. He had a Maxi-Mini Carpet Anemone (MMCA). It's not as nice as Gig'em's, but he and the OP, KeLusth, recently got me hooked on them.
As he was trying to get it in a bag, I asked if he had any anemone shrimp other than Sexy Shrimp. His normal answer is no, but he said yes. It was still floating in a bag as he'd gotten it a few hours earlier. It looks like a
Periclimenes species, but I don't know which, yet. So I got both the MMCA and shrimp.
They were in the same acclimation tub and the shrimp immediately sat on the MMCA (sorry, crappy pic with flashlight).
After acclimating, I put the MMCA in first (spot that my wife chose, or at least second choice after I vetoed 1st

) I tried to put the shrimp in on the MMCA, but it dropped down lower. It wouldn't look up to see the MMCA! You can see the shrimp below the MMCA (and above a little Mini, not Maxi-Mini, CA I've got).
I left it for a few hours, and it never moved or noticed the MMCA. But a Sexy Shrimp had come over and was eying the new real estate. I got a piece of rigid air hose and managed to back up the Periclimenes shrimp until it bumped into the MMCA. Then it climbed on, yea!
Shortly after taking that picture, I saw it chase off the Sexy.
I'm pretty excited. OP, copying is the sincerest form of flattery. You posted a great combo, thanks.
