awesome build so far!
i'd very much like to see your current "ghetto setup" for the salamanders- sounds intriguing xD
are your salamanders wild-caught?
only one problem i saw-
on the initial post, under "vertebrates," you had crayfish...
crayfish are inverts too :P
but really, this is something i'd like to do in the future... subscribing!
EDIT: why not add something to raise the pH (not chemical, natural... something calcium? limestone, maybe?) to the water?
