I have Hissers coming!!!!

[JeffreH]

Does anyone know about how hissers compare to dubias as far at nutrition? I would assume they would be pretty similar due to them eating the same stuff. Just curious.

Virtually identical. There is some nutritional data floating around that suggests that most feeder cockroach species vary insignificantly in basic nutritional composition. They will have varying micronutrient composition, so offering a variety of roaches or other feeders will still be highly beneficial for your pet. Later instars and adults (particularly males) are much more scleritized (harder exoskeleton); which tends to go hand-in-hand with chitin mass, so don't feed anything that is too large for your frog to handle as adult hissers are quite large and also have some spines/spurs on their legs . The nymphs make fantastic feeders... just remember they can swiftly climb smooth surfaces like glass and can squeeze out of very small openings.

My experience with Malagasy Hissers (G. portentosa) is that they mature at close to the same rate as Blaptica dubia - probably averaging close to 5-6 months to reach maturity after about 6 instars. Their gestation period is nearly twice as long as B. dubia (close to 2 months), but they also incubate oothecae internally and give live birth that can greatly exceed a typical B. dubia litter... probably average around 45 babies and as much as 60+ from a single mature female. This is somewhat speculation; I keep several hisser species for hobby and don't tend to keep serious records on them.
