I put in the table salt. The fish is not eating...so I bribed it with bloodworms. Got it to eat some. The fish at the fish store are all still healthy, saw them yesterday. The ph in the water in this town is 7.2 it does not vary at all. My tank temp is 80 degrees I am not sure what the temp is at the store. Thanks so much for all the info. I hope he gets better...he is so beautiful.
