No ... never touched him. I followed the acclimation procedures to the "T". He was in a bag with minimal water (didnt leak) and I slowly added to it over 4+hrs. I then took the bag out of the sump and submurged the whole thing never exposing it to air and just let him fall to the sand. Now its traveling all over and hiding. Probably one of the least expensive (12.00) additions that added great color to the tank.
