Let me guess, your Gar and Bicher lived to be a good 2yrs old and were happy right? The fact that you have asked for good information, been informed, and refuse to listen just shows you have gone from ignorant to just plain neglectful. At it's widest is a 35g would be around 12" wide, when a Ray will get over 18". How would you like to be shoved in a room to live that was 2'L x 2'W x 4'T room? I am sure we could hand feed you aswell, but that wouldn't mean you were happy. Also, Rays have a steady growth rate. Even a pup only 2 months old would be outgrowing your tank. If you can't properly house it, don't get it. And the tank would need to be atleast a 180g. Honestly I hope their illegal in your state. That would help you resist the urge.
