hey! so, i was wondering- can you keep madagascar hissing roaches alone (or maybe a pair of 2 females)? and if so, how big should the enclosure be? i would like a roach, but every website seems to think i want a big colony ! sorry if this is weird
You can keep them alone but they do better in a group. Many roach species are considered “presocial”, and some roach keepers have found that Madagascar hissing roaches tend to do better when they have competition.
A group of females would be fine!
It depends on which Madagascar hissing roach you get. Some are much bigger than others! Knowing which species you mean by scientific name would be helpful. I’m going to guess that you mean Gromphadorhina portentosa which is the common hisser and the one I’ve seen most often in pet stores.
Two females would do just fine in something like a large “critter keeper” tote, two and a half gallon aquarium, or even a large fish bowl (with a proper lid, they can climb glass and plastic!) or similar-sized tub. Bugs are one of the only animals I can recommend for small enclosures.
All of the large sized hissers would do just fine in this enclosure size. Smaller species, like a couple tiger hissers (Gromphadorhina grandidieri), dwarf hissers (Elliptorhina chopardi), or Halloween hissers (Elliptorhina javanica), would do well in even smaller enclosures, like a shoebox sized tub (1.5 gallons)!
Any enclosure you get should be at least double the adult’s size in height. If you get nymphs (baby roaches that still have growing to do) they will usually molt on vertical surfaces, so enough space is very important; otherwise they can have a mismolt, which can cause deformities and other problems.
Hissers like to climb, and will usually spend their time off the substrate. You should provide climbing opportunities like cork bark or other wood, fake plants, or even just strips of plastic craft canvas. They will climb the walls of the enclosure as well, but appreciate cover and hiding places.
Whatever you do, make sure you have a secure lid. An escaped hissing roach is unlikely to survive. If you get all females, however, you at least don’t have to worry about nymphs (babies), which are tiny escape artists.
Let me know if you have any more questions!
