i just got home from work it is dead. he was at the bottom this morning acting pretty normal....i moved the catfish last night, the water was a little cloudy but the parameters are still what they were before i put him in.
mine kept saying weird readings, i decided to check the expiry date.
i'd purchased them in late feb of this year..... they had expired early 2008. i was astonished. ever since i've ripped open the package and checked the expiry date before i leave the store.
Check your air supply. When mine was floating I couldn't take my eyes off him. Then I notice 2 silver dollars at the top of the water. Checked air and the bubbler had went out and they was gasping for air. Now my stingray is being normal.
