I noticed this morning that my JD was acting very strange. He is very motionless on the bottom of the tank sometimes listing to one side. He is the only fish in a 45 gallon tank. I gently prodded him with my net and he darted around for a bit and ate two meal worms I gave him but then resumed the aforementioned behavior. I did not check the PH but did a 30% water change last night. Heater is on and water temperature is between 78 - 80 F. He is about six inches long and I feed him a mixed diet of cichild pellets, blood worms, and meal worms. I am quite worried about him. Am at work now and will not be home till sometime after 8 pm CST. Any help or advice would greatly be appreciated.
