I finally pick up a salamander - the person who I go it from also gave me the tank that its in. I know that in the very near future I'll be changing things. I'm thinking of moving the crabs (along with the false bottom that I made) out of the terrarium and into the emptry 25 gallon in my room. Then I'll have a better tank to "play" in for the salamader. I think that I'm going to try a stream type - so that its water is filtered so it should be easier for us to look after. Not 100% committed to that idea as I do like the terrarium, but we will see - perhaps I can convince my husband to build yet tank stand and get a new tank
One can hope - here's the pictures of the newest addition to my room.
