Freshwater stingray

[Bret11]

What kind of substrate is needed for freshwater stingray and how many could I put in a 220 gallon tank that’s 72x24x30

Soft smooth sand or no substrate. Depends on the ray for size. Not many, and none for entire life span.

What kind of rays stay the smallest and until what size could they stay in my tank.

I would say your best shot is a hystrix/wallacei but even they get to 30-35cm and that alot of rays. Here is a pic of an bd x motoro hybrid im growing out he is about 22cm WD and the tank is 60cm wide.

Reticulata and histrix are the smallest at about 15" diameter.
