Terry, thanks for the advice. I have been moving the fish, when necessary, in a specimen container. I am bringing a battery powered air pump as well as a carboy of water to replace spilled/splashed water or do a partial water change in the bucket if necessary. I live about 60 miles from the vet, will bring fish into work, go to the vet for a 2:00 appointment, then go home.
Bob Fenner strongly recommended metronidazole and praziquantel. Others recommended various antibiotics. I am not seeing the typical signs of a bacterial infection - neither external nor systemic. I had a tough time deciding between what several respected and experienced people advised, and Paragon II seemed to be the closest to incorporating advice from several people I consider experts.
What Paragon II contains:
Metronidazole
Furazolidone
Neomycin Sulfate
Naladixic acid
I am using the recommended dose for saltwater (2X freshwater dose of 1 tsp/20 gallons). What I am really doing is flying blind. There are good reasons to follow your advice, or Puffer Queens, Bob Fenner's and others. But they tend to conflict. It's really all just guess work at this point.
So I am taking the fish to this practice in order to get a recommendation on what, if any, treatment may be effective.
I do have gentamycin, kanamycin, neomycin, triple sulfa, tetracycline (I know, not great for salt water). Rather than continuing to treat blind, I'll hope I get the fish to the vet in time for them to examine and make recommendations based on clinical evaluation.
I do appreciate your help very much. I am not one of those to ask for and ignore advice. It's just that I've received a diversity of conflicting advice from several people whose opinions I respect.
