I spent the entire day trying to catch him.and I am soooo happy I did. I had the fish trap in the tank for a week now and only feed through the trap with opened door. I sat in front of the trap for 30 mins while dropping in mysis every 5 mins. After 3 failed attempts, I finally got him! He flips rocks and frags on the sandbed. Buried my gold torch. Kept turning acans over. Killer of so many frags.
