Need more options for those of us with multiples 

  I'm 2 for 2 with good luck so far.
---------
- Macropharyngodon bipartitus
 
- Live Aquaria shipped, acquired 02/2007
 
- Quarantine by true definition of the word, not by hobby idea (dedicated temporary small tank, rock, sand)
 
- 180, over two years, LPS/SPS, etc
 
- First attempt
 
Roughly 2" when acquired and it has changed drastically.  Now almost jet black at roughly 5-6", yet the most peaceful fish in my tank.  I will try to get new pictures as I haven't taken any for a while.
(will add updated picture later of the change)
---------
- Macropharyngodon ???????
 
- Local acquisition from Phishy Business, acquired 05/2007
 
- Straight into the tank
 
- 180, over two years, LPS/SPS, etc
 
- Second successfully leopard
 
I have never successfully identified this one.  This one was roughly 2-3" when I purchased it and was actually LARGER than the bipartitus already in the tank.  Roughly 5" now.  After it was introduced to the tank, it stayed about the same size for a short time.  During that period, the bipartitus VERY rapidly went through a growth spurt and hit 4".  Almost overnight (seriously, overnight), the bipartitus changed from the colorful setup to the black colors.

Never even the slightest sign of aggression between the two leopard's or to/from other inhabitants.  All other wrasses steer clear and don't even attempt to engage in any form of hostilities.
Additional thoughts/notes:
If you can't get it to start eating, Arctic Pods are a healthy treat, and were almost instantly identified as delicious food by both leopards.  Within weeks they were eating mysis, flake, pellets, etc.
Obviously pick a good reseller and/or LFS to get the fish.  It's a very delicate shipper and deserves respect and proper techniques to ensure it's survival.
Absolutey, positively, no matter what, DO NOT DIG THROUGH THE SAND LOOKING FOR THE WRASSE!  I see thread after thread stating that a leopard has dissapeared and the user is starting the digging process.  1) If it is not doing well and/or is sick, digging through the sand is likely NOT going to help you catch it (as it will just re-dive in another location).  2) You're going to further stress the fish drastically.  Imagine being in a dead sleep protected, and being ripped out of your bed abruptly.  What would your reaction be?  3) They will take some time to acclimate to your setup. My bipartus took a while to understand the light cycle.  I would see it about 5-10 minutes before the lights turned off, then slowly longer, slowly longer, etc.  The second leopard was at the LFS, so was quicker to adapt.  Now they're both up about 10-15 minutes after the actinics turn on, and are sleeping before they go off.
