Well, here's an update. The largest of the three died. The other two were still eating as of a few days ago, but their eyes have progressed to the same point as the other. I contacted Mark Lucas (who I bought them from) and described the situation. He said that roughly 50% of this species get this at some point after acquisition, but what he has never aquired is a vaild diagnosis.
I have tried Melafix, Lamisil AT (Athlete's Foot Spray - Chytrid remedy), and now Methylene Blue dips (2ml per gallon / 1 hour soak / 3x daily)...all to no avail. In my opinion it is amazing that these things are still alive after all the **** I've put them through.
Today I force fed them each Panacur with an earthworm chaser. I think this is a naturally occurring parasite that simply freaks when stressed. Hopefully Panacur will kill it, but even if it does, I fear their eyes have been scrambled by the bug, whatever it is, and may never be the same.
This is an amazing species of frog, and the fact that they are rarely for sale as wc juvies, and almost never offered as wild caught adults, might just speak to both their sensitive nature in captivity and the reason that there is almost zero captive care requirements to be found on them.
I'll let you know how it goes.
Below is a link to a pic of a healthy adult female. If you consider that the plank boards pictured are most likely 4" wide...this is one aquatic behemoth.
