I guess I'll just have to keep an eye on him.
BTW....his name is Waldo, because when he first went in the tank he moved around so much (where's Waldo).
Well I tested my water, just to make sure everything was ok:
Sal - .025
NH4 - 0
NH2 - 0
NH3 - 20 I'd still like this lower (0-5)
Ca - 480
PO4 - 0
KH - 9
Temp - 78
ORP - 11
With my experience with BTA's, they'll split if they're very happy or if they're stressed. Since it was right after you moved, I bet that it was due to stress. Water levels look good..
