Thanks guys, She is fat for sure but she might be prego too lol
Both rays have been very active lately, they push the sand to the middle climbing the sides of the tank
I just leveled it out about a week ago too
He has been very gentle with her since around x-mass when he left a few nice bite marks and possibly knocked her up which makes me even more suspicious she is prego. She actually chews on him quite a bit more than he bothers her
