I am very sorry for your loss. I can relate to how you are feeling, with the flooding we had this summer I believe my local water treatment plant added something to my water supply. I lost 12 out of 13 of my motoro (3 adults of 2 mated pairs and 5 pups). My one lonely ray is holding on but I think I'll stay away from more rays for a while. Luckily, my 3 aros survived but I lost most of my salt water fish as well. Only the queen angel, blue tang and three eels survived. What a rotten summer and it is very painful to lose our pets. Again, sorry for your loss.
