My son has (bearded) dragons - two of them. No fire though but probably economic potential - growing popularity as pets (and very friendly/docile). Not really smallholding but you could 'farm' any of the live food that the reptile and bird market needs. We have to get live crickets for the lizards and I quite often get some live meal worms for the chickens at the same time. Lots of other buggy things you can buy. Husband was keen on snails until we saw them at a smallholding exhibition and I said he could get a started pack - seemed to put him right off and he wouldn't even hold one. Very odd, given the numbers round here, you'd have thought he'd know what to expect by now.
How about skunks? Make great pets, I believe - although, again, from the smallholding perspective, you can't really eat them - unless you're on 'I'm a celebrity...' and they don't do a lot else. Maybe you could harvest their scent as a fox deterrent....
