So I just rearranged my tank, made it easier to clean by adding decorative thick plastic rectangular large dish for swimming. Added another hiding place and am considering getting wood house like my hermits have. After seeing my frogs looking bored, I called a few pet stores to see if there are any critters I could add to tank. Basically I was told "no" even though one store houses FB's with red crabs. One store had baby tree frogs, size of about an inch, they said not to mix them. Does anyone have their FB's in with other critters? If so, would it be tree frogs? Is it true that FB's would try to eat baby tree frogs? They do not sell little turtles anymore (I'd really like some) so I don't think I have many choices. Any suggestions are appreciated, like I said my frogs look bored (I know they typically sit around or swim) but I sure wish I could add another creature for them.
