Hello, my cousin had stingrays long before i did, just started a month ago. He always had larger rays with larger rays, but he had given up ray keeping for about 4 years. He strated again which he has a small motoro like mine. My motoro is about 6in. at disk his I think is about 5in. He has a 180 gallon aquarium with just the motoro alone. I told him about aquascape where he soon purchased another motoro about the same size (there on sale now). His is coming like in about a week I think, don't know for sure. Well he doesn't have an account on MFK well he wants to know will thier be any problems with introducing a new ray with another ray the same age and size? Thanks
