Splitting Tiger Tail
 

hi all.
for about a week our tiger tail cuke was motionless near the back of the tank. on christmas morning we looked and noticed the front half going one way the the back half going another. here's a pic, i'm wondering if anyone else has experienced or heard of this before. both halves seem to be ok though aren't eating again yet.
