Steve,
I have never seen a bonded pair of Liopropoma carmabi available anywhere before. After working with numerous individuals, in a few different batches, I have had good success bonding up a few pairs.
Hopefully we will be fortunate enough to receive another batch of these incredible fish soon, and I will work diligently again with the group to try and bond up a few pairs if we are lucky. The fish that were sold in the Divers Den yesterday were together for well over a month, and resided in a cubicle on our main system, and hung out together in a piece of PVC pipe when they were not out in the open.
Cheers!
