Grey Tree Frogs need company ?

[irThumper]

Well with fish it's obviously not smart to mix peaceful community dwellers with fish that are aggressive. Certain birds can be kept in a mixed aviary, however, if, like the fish, they are matched accordingly in temperament, housing and feeding needs, etc. With hamsters some are community dwellers (certain dwarf breeds) while others, like the standard Golden variety, are solitary. I would never mix different rodent species together (gerbils and hamsters or mice and rats, etc). It all depends on the animals in question, but herps carry so many parasites, and have such differing needs that, unless you are in a zoo environment there is no good reason or ability to keep them successfully in a mixed group, in my opinion.
