Possible but do not know why.
Keep the water changes up and keep offering food, If it is showing interest then I expect it will get there.
Keep testing the water too
You might want to look out for some garlic based food as well (we can get it frozen mixed with krill here) as this can help build appetite.
Keep trying lots of different foods and do not let it fixate on just one, take out any uneaten food after maybe 15 mins but try not to disturb the ray too much.
Would still keep the lights off for a while and maybe cover part of the tank
