Please help!! My salamander has a big black spot and other tiny ones all over his body!

Hi guys, I'm hoping you can help me! I was up for hours last night searching for what my salamander has and saw this website. It seems like people reply quickly and I saw one story that had pictures similar to what Iggy has. I'm scared to death to take him to the vet after they told me they would do a skin biopsy that would need one or more stitches plus anesthetic. Does anyone know what this could be so that I have an idea of what to expect when I do take him in? I'm very new to this site and not sure how to work some things so I'll try to get pictures up. Thanks for any input!!
Oh, in case I can't figure out how to get back to this thread you can email at starwinter86@yahoo.com

Hi Starry,

It's hard to tell with those pictures, in the first picture it almost looks like a mass of some sort but in the second picture it looks like a discoloration. If it is at all possible. try to get a clear close up of the area so that we can get a better idea.

You may also want to consider changing his substrate, if I'm not mistaken they prefer something that they can burrow into easily.

There is some good info here http://www.caudata.org/cc/species/Ambystoma/A_tigrinum.shtml

Cheers,

Here are the pictures

The fact that you rubbed it off and it grew back and then vanished concerns me a little.
It looks like it scared or discolored the area. If it comes back I would place her on a thick layer of wet paper towls with a hide for a couple days. During this time I would rub a little antibiotic creme just on the area of concern. Or you could try doing salt baths.
You would soak her in saltwater twice a day for no longer than 15 mins at a time. This is very important!!! And do it for 5 days. I beleive the the salt water mix is 2 tablespoons of salt per liter of water. But you should check on that. His kiddy pool is huge for a salamander you could keep 10 in there. It looks a little dry in the picture.
I would be worried that such a large open container like that might dry out on you. So
just be careful. Is she able to climb out of it. The sides didn't look that high to me. The sides should be higher than she is long. They are escape artists. Their moist skin clings to plastic. I learned this the hard way once but was lucky and found him before he dried out. Good luck with her.
