What I stocked for cleanup crew and what I'd change a year in
I set up my first bioactive enclosure for a crested gecko. I had no real frame of reference for how much cleanup crew to stock or which species to use so I just went with what the guides recommended and adjusted from there.
Initial stock was a culture of powder orange isopods, a temperate springtail culture and a handful of dwarf white isopods. The powder oranges and springtails came from micedirect, the dwarf whites came from a local expo seller.
Here's where things stand now. The powder oranges are the backbone. They've bred steadily and they're clearly doing the bulk of the waste processing. I see them on the surface at night cleaning up gecko droppings and breaking down leaf litter. The springtails did their job quietly. I almost never see them but the substrate surface has stayed completely mold-free.
The dwarf whites are the one I'd reconsider. They're alive and they've reproduced but they stay deep in the substrate and I can't say they're contributing much that the powder oranges aren't already handling. If I set this up again, I'd put that money toward a larger powder orange starter culture instead.
The biggest lesson for me was that front loading the isopod count matters more than species diversity. A hundred powder oranges on day one would have gotten me to a stable colony faster than splitting between three species.
