I have 5 silver dollars ranging in sizes from 3" to 5" in my tank with 2 12" motoro. I hope they'll be alright. They've been together with the rays for about a year now and all has been well. I have checked the tank at night time before and never noticed any hunting behavior by my rays. I'm keeping my fingers crossed as I need the sd as dithers for my aro.
I have had 4 large discus with my ray for about 2 years and they are fine. I was stupid and tried to add two more that were smaller and at night discus sleep on the bottom and that's when they became dinner.
I lost a Armatus to my Ray. That was the only Tank Mate he killed off, unfortunately he was the most exspenisve. I still havent got over it. I have the armatus caracas in my freezer to remind me.
LOL!!! I kept my dead fish in the freezer and my wife yelled at me. Said I was a fish horder. Said she did not appreciate dead animals in her freezer so I took out all the chicken and beef momentarily and replaced it with live feeder goldfish. Hehe. She flipped! Not to say my marriage is the most stable, so I advise you to try this with cation as I can not guarantee a postive outcome. However, it was a damn good laugh when I did it.
