Last night as I posted in another thread that i got the Rays all tucked in to the pond and at 4 oclock in the morn i gor up to empty my self and went over to check in on them and the smaller of the rays was stuck to the suction 90 that goes to the pump i tried to push her down gently but I had to shut the pump down so it would release. I thought she would be dead in a couple of hours as she wasnt breathing to well. She was stuck right to her head over one of her eyes and one of the ports on the same size and I thought it sucked that eye out but today I can see its still there but she has a vacum circle 1 1/4" on her head and to make things worse they are both loosing their slime coat, like peeling off if you know what i mean. My amonia was .50 for some reason as its an established pond for 8-9 months and has been empty for 2 months (maybe the problem) so i did a 60% water change just now. The hurt one has a appetite still but the big male has no interest in food. Anyone have some real help???
