I noticed this morning one of my motoro rays had a stinger stuck in its back.It did not look deep so i took some really long tweezers and pulled it out.It was in further then i had thought.Now the ray is lifeless just sitting in the same spot for hours now and breathing faster then normal.I do not see any redness or swelling and i can not even see where exactly i pulled it out from.Is there anything i can do for him?Thank you ahead of time.
