its a 55
gal tank. and the water is good. i have this thing to check it at home
But that doesnt state what the levels are now.. That Thing hopefully is a master test kit of some sort.. Fish do not die for no reason.. there is always a reson to their deaths.. A 55g is no where near big enough for Any Ray out there..
if i take some rocks out will it be safe?
To be painfully honest no it wont.. I would say that It would probably die in about the same amount of time..

here is about a general statement that could be used for just about all Sting Rays
Due to its lack of hardiness, the Spotted Caribbean Stingray should only be kept by an experienced hobbyist. A 180 gallon aquarium with at least a two foot width from front to back is necessary for an adult. It likes to cover itself on the soft substrate as camouflage. A coarser substrate will scratch its abdomen and could cause an infection. It should never be exposed to copper-based medications. It will eat any crustacean or mollusk in the aquarium.
Again Please dont buy the Ray They really belong in the wild not in an Aquarium
