Bad price on the blue spot good price on the yellow ray. My lfs sells both blue spots and yellows for $60. Neither will do well in your 120 if thats where you plan to keep them.
Don’t think so? I had the guy at my lfs tell me that a Bamboo shark and a small Caribbean ray would be fine in my 120 (I believe you more cause I think that he is just trying to make me buy crap.) What would you say the min. tank size for a ray is? At least 6 feet long right????
The length isn't the problem, its the width. These rays have disc widths of about 11in(blue spot) and 14in(yellow) when full grown. For either you'll want at least 24-30in of width and 5-6ft of length.
