I purchased a very nice 8 inch female marbled motoro from someone on here and here is my story. I picked it up from the airport brought it home did the drip acclamation for about 2.5 hours. The ray looked like it was doing ok breathing was not to fast, and i swam around a little bit. I went to sleep got up early in the morning excited to check her out and she looked good then too. Went to work came home and she was DEAD. What i want to know from you guys is what could have caused this. I know what im doing i have had rays for years but nothing like this has happened before. Very sad day for me i have been looking for a marbled female like this for a while now and she is gone.
