Absolutely gutted. Came down stairs this morning to find this ray dead. just sitting at the bottom of the tank. No signs of anything. No death curl at all. All water parameters fine, and before anybody asks i check daily using both electronic and in date, liquid test kits. Ph 6.5 , NH3 0 , NO2- 0 , NO3- 30 , KH 8.
All other rays, including my three newborn pups, and fish absolutely fine in both tanks which received exactly the same water and food yesterday. Completely baffled by this one.
I might do a dissection to see if i can find anything abnormal internally, but not sure i will have time due to work deadlines.
