It's been semi shriveled up & hard looking(if that makes any sense,that's the best way I can describe it),for like 4 days now. What should I do? Levels are as follows,PH:8.2,ammonia:0, nitrites:0, nitrates:0, calcium: 500,dkh:8deg,phosphates:0,magnesium:1200ppm,specific gravity:1.025. It hasn't been right since I got it from the petstore about4 weeks ago,it has eaten a couple of times & I thought it was on the rebound but now I think it's on it's way out. Any suggestions as to what I should do would be appreciated.
