I recently bought a nice EBJD. He was in my QT tank for 2 weeks and was then added to my 75 gallon to pair up with one of my BGJD females. He has not eaten since I got him
I have a feeling he has internal parasites since I can't see anything on the outside. He does not have a sunken in belly though. I have tried treating the tank with metro but there has been no improvement. Water parameters are good and 50% weekly water changes are done. I've tried every kind of food mixed with the meds to try to treat him be he won't eat anything. He hangs out near the surface of the water(plenty of oxygen in the tank) and goes between normal coloration and being dark colored. I paid a lot of money for this fish and I really don't want him to die. I've added salt to the tank, raised the temp, treated with metro/prazi and still no improvement. What else can I do? How can I get the meds into him?
