Hello everyone,
I keep a array of different herp species for educational outreach programs at my university. One of these is a breeding pair of Notophthalmus viridescens that I raised from eggs gathered during a zoology field trip in 2018. The eggs were found in Greene Co. AL if that info is relevant. I kept a male and female from the larvae that hatched and released the rest when they got older, and those two have been living happily in an aquarium ever since. Over the last year or so, the male has developed these protrusions on his shoulder and chest (pic provided). They don’t impede his movement or behavior at all (he feeds normally and successfully bred the female this year and has eggs on the way right now).
If anyone knows more about what this could be, let me know. It’s most likely not diet related, because the female has been raised on the exact same diet as the male since day one.
They eat a diet of Omega One Newt and Salamander pellets and the occasional bloodworm packet or mealworm. They live in an aquatic set up 5 gallon aquarium with an internal mechanical filter (temporarily removed and replaced with an air stone for the eggs’ safety).

    Dear All, I would appreciate some help identifying P. waltl disease and treatment. We received newts from Europe early November and a few maybe 3/70 had what it looked like lesions under the legs- at that time we thought maybe it was the stress of travel- now we think they probably had "red leg syndrome" (see picture). However a few weeks later other newts started to develop skin lesions (picture enclosed). The sender recommended to use sulfamerazine and we have treated them 2x and we are not sure they are all recovering. Does anyone have any experience with P. waltl diseases and could give some input on this? Any input would be greatly appreciated! Thank you.
