Cane toads (Bufo marinus) definitely fall on the "bigger" side of things. Someone can call me out on this if I'm wrong, but I feel most Bufo are pretty easy to care for, if you make sure to actually read a care sheet and stick to it. No need for specialty bulbs that need changed. Room temp is almost always fine for them, so no need for heaters and a thermostat. A timer for their light is good, but that costs like four dollars. You need to dust their food and make sure they have clean water, but that's about it. Mine might just be a punk, but I swear she even prefers more spartan cage setups than the fancier things I've tried in the past.

Ironically, in terms of food expenses/diversity, hardware, time spent daily, and space required, the roaches/crickets I raise for her food take far more effort.
