So turns out the "female" ray I got was an underdeveloped male. I called the LFS at 1852 and they said bring him in and they will return it. They close at 1900.
I brought him in at 1910 and we made the swap and placed the order for a REAL female. They gave me (2) 8" bichirs, an 8" black ghost, and a 5" bushynose pleco. That sure balances it out, I've still got $20 in store credit too
He tried to convince me to get an 8" arrowana, no way. I explained my tank size and he retracted his arguement. They did have an awesome royal knifefish, but he was pretty pricey.
