I second what ZooDiver said. I originally had an air wand in the tank, but it didn't seem to help much. Once I lowered the water level and all 3 filter outputs were dropping farther into the surface and plunging bubbles about 6-7" downward into the water, she really seemed to perk up and feel better. Also, the taco thing really isn't a HUGE deal unless she's physically shaking or it seems like she's stressfully and tensely pulling into that position. If she's just hanging out like that and seems chill, then don't worry so much. Macy would do it sometimes just for the heck of it but her disc would be loose and relaxed. The rigid tacos were the ones that made me quickly figure out it was the oxygen level.
Also, I want to add that ZooDiver is definitely one to listen to regarding sabinas. Everyone on this forum was a big help to me, but since sabinas are quite a bit different than the true freshwater stingrays and what applies to the true freshies doesn't seem to always apply to these, ZD's advice has been a huge help. Since he works with animals like this professionally, his experience and knowledge is invaluable.
