ok.. so maybe you saw me post last week.. i bought a femal motoro an she had a dent in between her eyes i did a big waster change 3 days after having her an then added prazi pro as recomended in a similar posting.. saw a lil wierd movement with her disk going upward lookin like a siezer almost.. excuse my spelling.. but then it went down i went to bed an wake up to a dead stingray. my male was like showing her off to me by swimming over her fluttering his disk very fast an vigorisly she jus floated an i noticed she wasnt breathing... really wondering wat happend here....my water has been tested constantly an comes back great..wtf..sad, angry ,an some more.. was only 9 days she ate several times. not a ton but she did eat..
