Hello:
I'm so sorry your previous post received no reply...good job on noticing right away when the frog became symptomatic and acting quickly.
I do have a few questions:
Did your white's have red legs prior to using Melafix? How are you preparing the melafix and applying it?
Was he only experiencing runny, smelly stools prior to quarantine?
There is obvious digestive issues. Parasites? Bacterial? Viral? I would have no idea (no one would), but a VET can perform a stool test, and I HIGHLY recomend you do so. It costs about $20.00. And the vet will then provide the APPROPRIATE meds to treat the problem.
I would recommend you discontinue the melafix, in whatever way.
I keep both fish and phibs. I only use melafix for my fish, and only 5ml per 10 gallons. Too much will cause death in fish. My guess is your frog's skin is very irritated due to the Melafix and causing 'red-legs'. Melafix is for bacterial infections in fish, not for frogs. And, your frog may have runny stools from something other than bacteria any way..
You need a vet, Dr. Frye is wonderful (if you do not have a herp vet locally).
I also recommend you add a plant to the hospital tank, artificial ok, to provide a little more security to the frog. and perhaps cover 3 sides of the enclosure.
Discontinue meal worms, perhaps only feed night crawlers, if he'll take it. Cut to about one inch and fed with your fingers or tongs, wiggling slightly to entice his appetite. and Small crickets are ok for now.
