Disastrous first split cage intro
I introduced my new girl to her potential cagemate via split cage today and it was an absolute disaster. They were jumping at each other, charging and attacking the cage within literally less than two seconds. They actually broke the screen and were trying to death ball within literally seconds of being introduced. They both escaped while I tried to separate them and I had to spend five minutes chasing and keeping them separate in the living room before I got new girl back in her tank. She's now been arched and defensive in the corner of her tank for the last hour while OG has been super-territorial.
Is this normal and likely to be fixed through normal split caging, or is it doomed from the start? I don't want to give up too soon but it's still early enough to rehome her if this is actually dangerous.
