I have had 4 hadrurus spadix for over a year. Until now they had been getting along great. I have been keeping 2 each in 10 gallons. They had always got along and never fought. I even kept all 4 in one tank while setting up a new cage with no problems. The last few weeks one has been grabbing another by the tail and trying too drag him all over the tank. Then when I feed him last he grabs a cricket has it in its mouth and is running full speed all over the place with the cricket in its mouth. So I did remove him. Has anybody else ever experienced this behavior with any hadrurus species
