Hi Pip,
Thanks for checking-in. She's nose-up and not on her side ALL of the time, and her tail is still mostly on the bottom of the tank. She seems to have figured out a means to stay upright, basically, resting herself against the side of the tank, in-between the glass and a plant.
I see this as a tremendous improvement; the 15-20 minute soak/salt baths treatment have been extremely beneficial.
Occasionally, she takes to a brief, arc, swimming up to the top, maybe swimming a sideways circle or two, before gently settling back to the bottom.
Also, I've noticed a dark gray ring around the base of her left eye, and it's popping ever so slightly out further than it should. This isn't good, and suggests another parasitic issue.
I've removed the charcoal element from my Fluval 206, and treated the 29 gallons with 1 1/2 teaspoons of PraziPro, which is the recommended dose.
Also, I've established a 10 gallon rehab tank for her, the tank is cycling at the moment, nothing in there at all, no gravel, no decoration, no plants. The filter is an HOB Aqueon but I'm not using the ready-made filter element with it. I've wrapped a bunch of polyester poly-fill around an element of the filter, and filled the main compartment with ceramic bio-mech. I'll transfer her into this tank later this evening. She should have some kind of a shelter to be near, I'm going to use a coffee mug or two on their sides - as a make-shift reef for her to feel secure around.
Both tanks have been treated/conditioned with Prime and I've been doing 40% WCs on the 29 gal tank every 6-7 days. The 10 gal tank was just set-up today. Once she gets added, I'll begin low-doses of salt in that rehab tank.
I have a T.C. Tetracycline (by API) and I've got some Seachem "Metronidazole" at my disposal, but I don't know if either of these are good to treat her swim bladder issue. I am quite concerned about this slight popeye issue now.
I just don't know where all of these maladies are coming from...
Oh, one last detail: during today's 40% WC, I did a thorough Fluval clean-out (except for rinsing the bio-mech). This included taking the intake and return-feed hoses into the sink, and rinsing-out a huge amount of built-up brown algae-like scum which has accumulated inside those hoses for the past 5 months!!!! Lord only knows what bad bacteria were living in that stuff. OMG!
Once I restarted the Fluval, WOW!!!! I had such an AMAZING increase in flow rate, it was like I'd purchased a new filter, one with twice the capacity of what I'd had prior to this extensive clean-out. Those hoses were disgustingly clogged.
