Your toads do not appear to have chytridiomycosis, but I can't tell if they are infected by chytrid from the pictures that you provided. It is always a good idea to quarantine and monitor wild-caught or captive-bred amphibians in separate tanks in the beginning (probably for at least one month) just in case one infected animal does not infect the other. Louis is right on about excessive sloughing in an infected animal. Lack of appetite and lethargy are also good indicator of presence of chytridiomycosis.
