They are a tropical, so they are sensitive to water temp. 55-56 is the
lower limit they can stand.


Yup, I did some checking out on that. Was also worried they would harm any
fish I have in there but was told if kept fed they should be ok, so I may
consider getting and putting one in. Is odd that I don't even have them in
my aquarium since so many do, but I find my bala's like eating off the
bottom, so didn't want to give them competition.
