.Coastal carpets have the potential to get fairly large as well... but are not nearly as heavy bodied as a burm would be. Carpets have a reputation of being snappy as juveniles, but calm down once they're large enough for birds not to confuse them as worms

My experience with burms has been 1) as others have stated, very strong feeding response, and while they are typically kind of bumbly, they can react quickly to something they perceive as prey. 2) very good about handling, pretty easy going 3) only really cranky about being removed from the habitat...lots of hisses or body flails, but never any strikes.
