What do you recommend as the best invertebrate pet after roaches? I'm looking for an inexpensive, easy to care for, and unusual-looking invertebrate. (I'm not a breeder, I keep them as pets.)
Hermit crabs have requirements like tropical reptiles, and fids and crayfish need a proper palludarium and all the workings of a tropical fish tank. Don't get me wrong - all are easy to care for once you read up on them and they are great pets, but they are not inexpensive. (Boy, did I learn that the hard way!) Start-up costs are a bit shocking, although maintenance costs are relatively low.I forgot hermit crabs, crayfish, tadpole shrimp aka "triops", and fiddler crabs.
