How long have you had these ADF's, Froggy?

I also noticed that you have a ton of bloodworms in with them... that could be fouling up their water very quickly which may exascerbate the problems. I'm not sure how much ADF's eat... but I would only put in as much as they should eat.

This is probably not related to the problem either... but I think the water is a bit too cold for them... I think they are tropical and do best in temps 75-80F. I know you're planning on rehoming them... but keep this in mind if you are keeping them.

I'm sorry I can't help with the problem with his mouth... but I can link you to good FAQ's for ADF's which may help you some.

Some ADF experts should be along soon.
