I caught my brittle today! He is usually hidden in the rocks but today he was way out in the open so I took my chance. Now hes in the sump. The reason I wanted to do this is in the 125 I found him in the "fish killing stance" where it was up like a bar stool waiting for something to go under it. Plus he just massive and knocks eveything over. Hes probably in the 18 inch range. My serpent is still in the display but it is alot smaller. Maybe 10".
