So I live in the east coast and fall is coming. Meaning seafood tends to become more expensive and i need to stock up. What is a good staple i should be feeding my motoro Rays? I have pellets but they dont touch them so i tend to put them in silversides and w.e i can stuff them in. But As a novice stingray owner, what is a good cheap staple? I am currently more worried about their weight management rather than their overall nutrional health right now... do anyone have any suggestions on what i can use as a staple? My rays seem to have trouble with Frozen Market shrimp. they chew it but they spit it out afterwards, i believe it is too tough for them.
