Weird things found in water dish

[dixychickca]

I have been finding some weird things in my tiger salamander water dish; soft things. Is it feeces, or can salamanders get sick while in there water dish? I used coconut mulch as dirt, is that what it could be? Any help will be great. Thanks.

Most likely feces. Just clean the water dish each day and you are good to go. Perfectly normal.
