I purchased a California Ray a few weeks ago and seems to be doing fine, eating well very active. Today I noticed it arched up somewhat and its disc a little curled around the edges and then went about swimming around its pond 60" round pond about 100 gallons for now. I remember reading someones forum about some ray getting the death curl and thats why i am concerned. I dont see anything visible on the ray like sores although its dung is kinda rubberband looking or a little stringy. I dont know what it should look like. Any help would be appreciated.
