Ill show you mine if you show us yours..
We also picked up a new Motoro almost a week ago also. He is a male and is about 5" to 5 1/2". I got him also at a really good price. But I know the LFS owner well and he is more of a salt water man than a freshwater and doesnt have alot of exp with rays. He had alot of intrest in it, but for two weeks no one picked him up, so he decided to let me have him for what he paid. So 75 bucks later, he is a new addition to our family. Wife of course said, ANOTHER ONE when I got home, but she loves all the fish we have, she even bought my two aro's for me as a surprise, so having more is ok with her.. As long as she has her angel tank, she is happy..
Good deal on your ray my friend, cant wait to see pic's of him. Keep us informed on how is is getting along.
