dying african dwarf frog

ammonia, nitrite, nitrate readings? tank cycled? regular water changes?

I have a well established tank and I can't keep ADFs for anything. Can't figure out why...

what are you feeding them? They need a varied diet and most people tend to just feed them one thing all the time which causes them to become bloated and other problems on top of that. I have 3 and have kept them for almost a year in my 20g without any problems but i vary their diet. I feed mine softened shrimp pellets, fish flakes (regular and spirulina flakes), freeze dried bloodworms and freeze dried tubifex and they seem to do well on those. Also, I never feed them day after day...I always skip a day or two of feeding. I've read that it helps with their digestion or something and so far they're staying alive and healthy for me. How are you feeding them because unlike fish they don't come up to the top as you probably know already. They have really bad eyesight but excellent smell so the food should be near them so they can find it. I have to target feed mine with tweezers to ensure that they are getting something to eat because all the other fish eat it before they can get at it. Its kind of a pain but oh well. Also, they are not tolerant of any chlorine in the water at all! The water you replace after doing water changes must be dechlorinated with some kind of dechlorinator (AquaSafe, Prime). The store I work in used to just put water in the tanks straight from the hose and it ended up killing 4 of 6 dwarf frogs in the tank at the time. Now we dechlorinate the water to prevent this. Hope this helps...there is a good site that another member recommended to me once for ADF diseases but I don't remember it. You could just try searching google for "ADF Diseases" and see what comes up.

Oh my. Sorry for your frogs !
I have 2 adorable clowns ADF frogs.
I can tell you what I do because I don't know were you are wrong.
My frog were in a 20g, 10g and didn't mind. Now they live in a 10g with a betta male. Tank is cycled and I use Prime as declorinator.
My frogs are hand fed with a droper. They eat blood worms and brine shrimp. They got big and look healthy. I have frog pelets but they don't get them.
Bloating could be dropsy so bacterial. I can tell you that my frog were able to take a Maracyn2 and a Maracyn Plus HALF DOSE treatment (because of the betta fin rot). Maybe you should try it. I wouldn't expose them to full dose treatment. BUT check water parameters first. If the water is bad .... that's it.
Good luck.

Mine won't eat anything but the tubifex or blood worms. Mine has been alive for a long time, including a month in a smallish tank with a Crawdad. The Crawdad will catch the frog, then let it go. Don't know what the deal is (frog is 100% unharmed).

i would be more suspicious of the disease chytridiomycosis.

This fungus lives on a frog’s skin, and is spread by an affected frog being in the same tank with healthy frogs. It is spread by fungal spores that pop off the sick frogs skin, and attach to healthy frogs skin, where it replicates.
Symptoms can vary from the ADF having tattery sheds or very bad looking skin, trying to climb out of the water, spazzing/thrashing at the surface, not eating, floating or hiding all the time, and finally death almost 100% of the time.

Its a frog specific disease, so any future fish are not at risk, but your other frog will most likely get it as well.
I, too, would check your water parameters closely as it could not be chytrid however its becoming increasingly difficult to find frogs that have not been exposed to this disease.
