Not sure if it's the right gen but I will give it a shot.

I have a 3 foot vivarium with pillow moss and cork bark everywhere. The substrate is a 1:1 mix of choir for gecko setups and tarantula sedge peat. Moisture levels can drop at the lowest to 65% but average around 75% to 87%. Temperature remains stable at 21°c on the cool UV end of the tank with a dryier peak of 28°c on the other end (although 25-26°c is the average). The only denizen in the tank is a juvenile african bullfrog who is getting on comfortably for the most part. With these conditions could I support porcellionides pruinosus along with springtails if I include daily food and occasional calcium and if so could leaving fruit/veg pose a risk to my bullfrog? Can I just sprinkle calcium powder onto the fruit/veg instead of leaving cuttle bone? I had the option early on to go with a bioactive substrate but chose not to as I thought I wouldn't need vegetation or CuCs, but the idea of having grubs that could eat droppings, loose hopper legs or keep mold down is sounding more appealing to me (and some of these isopods look really neat).
