2015-3-6 QT fish

pH 4.0 in QT.
All fish have resumed eating.
The constipation that developed resolved with MgSO4.

2015-3-3 QT of 3 fish

Sam,

I’d like to go ahead and send one of my affected fish to Dr. Baumgartner.  The coral colored one which is blind in one eye has lost so much weight I’m not sure he can recover.  He is eating a bit.

I have QT 3 fish that were not eating normally and had lost weight.  I have tried an experiment and want your thoughts.

Jack Wattley is a discus breeder and expert of many decades.  He’s written about an antimicrobial approach that I’ve occasionally used with success by lowering the pH of my QT tank gradually to 4.0.  Discus tolerate this well but bacteria don’t.  All 3 fish have started eating better but this may be temporary.  I found a scientific article that tested TB mycobacteria can handle pH down to 4.5 but not 4.0.  My question for you is will lowering the aquarium pH to 4.0 result in a pH of 4.0 in the fish where the presumed mycobacteria are?  I know they are extracellular pathogens.

Your thoughts?

Thanks,

Carey

To add:  fish started eating better and the ARSG started head-standing this am.  Tx for constipation.
