I'm trying to see where I was wrong. I bought a 2nd tiger salamander and put it together with my other one in a 20 gallon tank. When I received the other one it was still in the process of morphing since the gills were still there. As soon as I transferred it to the enclosure it went to the make shift water pond I made. First and Second day it would go in the water and out of the water. For me this was a normal process. Appetite was fine since the first day I fed it red wrigglers and devoured 4. 2nd day was the same as well. My 1st salamander originally made a burrowed tunnel where she goes in and will just come out when she's hungry. On the 3rd day i saw the 2nd salamander went inside the tunnel and that was it, I never saw it again. First I thought it was normal and would come out when its hungry but then it went days that I have not seen the 2nd one. I never bothered looking for it since my 1st salamander was in and out of that burrowed tunnel as well. Just today and its already 2:30am just had the urge to look at my enclosure and noticed a lot of springtails are gathering in one side of the enclosure. To my surprise I saw a maggot at least 2-3 maggots. And I knew something was wrong. I transferred my 1st salamander to a separate enclosure for now and started digging and cleaning the 20 gallon tank. There I saw the 2nd one almost gone (like it melted) Only thing I saw was like bones and it stinks!!! It looked like its been dead for days. Can anyone explain to me how this can happen? I thought that you can put tiger salamanders together? Did the 2nd one got lost inside the borrowed tunnel and couldn't get out??
