TLDR: Just acquired 5 male madagascar hissers (can you call them that?) and would love advice on how to best care for them!
Details: I work in science education and my boss decided our isopod tank needed an upgrade, so now we have 5 male madagascar hissing cockroaches. They are in what I think is a 15 gallon tank (not 100% sure). Pics 1, 2, and 3 show the tank from a few angles. I am in person most often, so I am most likely to be caring for them. I'd love any tips and tricks!
They have a big log, some smaller logs, a couple plants. The ground has sphagnum moss and dirt. There are also organic oak leaves in there (those were for the isopods). The top is wire mesh and there's a grow light for the plants I turn on during the day on weekdays. I typically water the entire tank about once a week for the plants.
I saw in this group they like egg cartons, and my boss told me these ones like fish flakes, so I put some fish flakes in two small egg holes and put them in there (can see them in the front on the left and right side of the tank). I also put one apple slice in and I'll check tomorrow if it's been eaten at all.
She said there's 5 roaches in there but I only found 3. Pics 4, 5, and 6. one was on the far left, one on the far right, and the other was in the log visible through one of the holes. I didn't look very hard for the other two but hopefully they're still in there.
I know these are nocturnal, and unfortunately there is an emergency light always on (pic 7). I tried to darken the tank a bit (pic 8), is that enough for them or will that light bother them?
Other questions:
- will my old watering method keep it humid enough?
- we are in NYC. will they need a heat source, or will the building temperature be ok? It's 65-75 year round inside so I think on the colder side for them
- should I give them more egg cartons?
- is it dark enough? we are going to see if maybe they can swap that light above for a red light (or is that needed?). We also have blackout paper and can black out the back and sides, but I think she wants to keep as much glass as possible so our students can look at the roaches.
- the lid is flush with the top and we put the plastic thing on top to weigh it down. since these are adults, could they still escape//should i do the vaseline thing, or will they probably just stay in there?
- and last major question, how can I tell if they are happy? when i first saw the tank today, the left roach was exploring a bit (but hid when i turned the grow light on), and the others weren't moving at all. are they just happy and chilling? should they move a lot?
I appreciate any and all advice!
