BTA just split!

[G1GY]

My BTA just split, so I was wondering if it's normal for a small fairly recently added BTA to just up and split? Do I keep feeding them both as normal or give them a few days rest to get adjusted? The first one likes to move around allot and roll itself into a ball every couple days or so at night.

How often do they do this? (I hope not too often.)
Is this a good thing? (First BTA I ever kept.)

Any info would be very much appreciated.
